Homework Help: algebra

Posted by jessica on Thursday, May 31, 2007 at 2:05am.

please write an explaination why (x^3)(x^4) is not x^12. I am confused thank you.

it is not the answer because, first of all, try replacing x with another number, in this case, let's say two.
(2^3)(2^4)= 128, and if you try 2^12, you do not get 128, instead your answer would be 4,096. The same with any other number. so try finding the number that would fit in. I found (2^7)=128.
so now try another number, 4.
(4^3)(4^4)= 16,384 let's check that. 4^7= 16384. so it wouldn't be x=12, it would be x=7. try replacing a variable with different numbers.
