simplify

(5x^2-3x-8)??
Answered by JJ
You can't simplify because there are no like terms.

Do you need to factor this?? or are you just being asked to combine like terms.

If you have to factor it. that is possible. Let me know.
Answered by caren
actually it says by using the laws of exponents?
Answered by JJ
By using the law of exponents, we cannot combine anything because the terms are all different.
Answered by caren
I'm sorry that was the wrong problem
is actually
(5^4 * 5^7)/5^8
Answered by JJ

so keep the base of 5 and add the exponents for the multiplication.

that gives you 5^11/5^8

For division, keep the base of 5 and subtract the exponents.

What is your final answer?
Answered by caren
5^3?
Answered by JJ
Yes 5^3 or 125. I am not sure how your teacher will want the answer.
