simplify
(5x^23x8)??

algebra 
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. 
algebra 
caren,
actually it says by using the laws of exponents?

algebra 
JJ,
By using the law of exponents, we cannot combine anything because the terms are all different.

algebra 
caren,
I'm sorry that was the wrong problem
is actually
(5^4 * 5^7)/5^8 
algebra 
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? 
algebra 
caren,
5^3?

algebra 
JJ,
Yes 5^3 or 125. I am not sure how your teacher will want the answer.

Thank you
