simplifying?
Q. e^(1+ln x) i know that e and ln would normally cancel out but the 1+ is throwing my off a bit. I really need an explanation of what to do if there is hte 1+ in there, because I have to do more problems similar to this and I want to learn how to do it instead of just getting an answer. THANKS

A. Try simplifying it down to something that makes more intuitive sense. How about this: 2^(3+2) = 2^5 = 32 sure, this is just the most obvious way. How about: 2^(3+2) = (2^3)*(2^2) = 8*4 = 32 ^^crucial step^^ Your example works the same way

A. If you have x^3-2x^3+2x^2-3x^2+4x^2+7 , it is better to write it as -x^3+3x^2+7 , because if you want to evaluate it for x=2, it is easier. Also , when you want to solve x^2-5x+6=0 if you write this as (x-3)(x-2)=0 then we can solve x=3 and x=2 easily. Here, we factor it (which is another simplification).

A. They are simplified by "rationalizing" the denominator...I use quotes because usually rationalizing is use to refer to taking out square roots...but it's the same idea. You may have seen this with square roots: 1/(1 + sqrt(2)) Multiply by conjugate: (1 - sqrt(2)) / (1 + 2) = (1 - sqrt(2))/3 The conjugate works because of differences of squares: (x + y) * (x - y) = x^2 - y^2 So comlex numbers work the same way: You can "rationalize" the complex number by multiplying by it's complex conjugate (just negate the imaginary part): (a + bi) * (a - bi) = a^2 - (ib)^2 = a^2 - (i^2)(b^2) = a^2 - (-1)b^2 = a^2 + b^2 So...that's how you get rid of the imaginary part in the denominator...someone else already gave you an example.

But sometimes, you still have to simplify it further, and the final answer I arrived to seemed like it could still be simplified. Si I simplified it again and got the further simplified answer. But then after a while i realized it was incorrect, and that I shouldn't have simplified it any further. Any suggestions?

How do you rationalize the denominator when simplifying a square root?
Q. I know how to simplify square roots, but I don't know what rationalizing the denominator means.

How do you simplify simplifying expressions in algebra?

A. -36 + 74r - 53 + r A way to begin, if you find it helpful, is to rearrange the order so that constants are next to each other and variables are next to each other. When rearranging, just keep the symbol that is already in front of it. 74r + r - 36 - 53 Now it should be a little easier to see what steps are needed to simplify this expression. 74r + r = 75r ( r is the same as 1r) -36 - 53 = -89 When we subtract from a negative number, it's like you are adding the two numbers and then putting a negative sign in front of it. We are left with 75r - 89. Hope this helps, let me know if anything is unclear.

A. Your right, one is with two pairs of brackets or in some cases, one pair and that is factorizing. Simplifying is when you literally simplify the equation down. When your factorizing you will normally be given an expression whereas when your simplifying you can be given the brackets so its easy to work out which one you need to do anyway.

Is the answer always negative when simplifying a number that has a negative base and negative exponent?
Q. I was doing my homework and I can't remember the rule for when it's a negative base along with a negative exponent. One example problem is: (-5)-2 (negative 2 being the exponent). It would be 1/25 but would it be negative 1/25. I know that if the negative sign is outside of the parenthesis then it would be a negative. Also would there be a difference if the -5 was in parenthesis or not?
Asked by Ms. Muffin-man - Mon Feb 23 23:06:40 2009 - - 1 Answers - 0 Comments
A. well, a negative times a negative is positive, so if the exponent is even you will have a positive number. Negative exponents just mean take the reciprocal of whatever it would have been with a positive coefficient. ie (-5)^(-2) = 1/((-5)^2) That's if the negative is in parentheses; otherwise, do the exponent like a positive and make it negative afterward. Fractional exponents are hairier, if I remember correctly.

A. Prime numbers are numbers that are divisible by themselves and by 1. Examples are: 1,2,3,5,7,11,13,17,19,23, 29,31,37,... so when you are simplyfing fractions, you want to be sure that the denominator is a prime number whenever possible. Hope this explanation helps.

What do I do next with simplifying this logarithmic exponent?
Q. e^(ln3 - ln2) e^ln(3/2) e^(1.5) What do I do next to simplify it? But I don't understand how it becomes (3/2) or 1.5. How? So we have to use a calculator to determine if the answer is 1.5?

A. e^ln(3/2) = 1.5 not e^1.5 so fix it and ur done !! its a formula , whenever u have e^lnx = x or ln(e^x)=x

What's a really quick way of simplifying fractions?
Q. Say you have 5550/298025 What is the quickest possible way I could simplify this fraction without a calculator? I already have the answer, but it took a lot of trial and error which I couldn't do without a calculator. You don't say.

A. Start breaking it down bit by bit by the biggest number you know both are divisible by. 5550 and 298025 are both divisible by 25 since both end in numbers divisble by 25. That gives me 222 and 11921. Now 11921 starts becoming difficult to reduce because it is not divisble by 3 like 222 is, because the number don't add up to a number divisible by three. And it's not divisible by 2 either. So now it's best to factor out the smaller number and see if any numbers left in the factor will divide into 11921. First we know it is divisible by 2 which gives us 111. Then we know it is divisible by 3 since the ones add up to 3, which gives us 37. And 37 is a prime number so we are done factoring 222. So since we know 11921 isn't divisble by 2… [cont.]

Does simplifying your life make it both cheaper and better?
Q. Good grief! Where am I ever going to find the time to do that? Probably it will take me the next 10 years.

A. Cheaper? Probably. Better? That depends on the individual. For instance: my vacations are usually right here at home. I have everything I need to enjoy my time off; my husband, my dogs, my garden, my pool, my hammock and all the iced tea I want. At night we like to build a fire and drink beer or cheap wine. We will play cards on the deck. We will swim with the dogs. We will star gaze on a blanket in the middle of the yard during a meteorite shower. I'll go to bed as late or as early as I want and get up as early or late as I want. I may even take a mid-day nap. For me, this is a perfect vacation. For me, it is BETTER than joining a rat race of a vacation in a resort area. But for others, it would be a miserable vacation… [cont.]
