It is for Algebra 1 CP. I need to understand this certain standard because my EOC is coming up soon. Thanks.

Lauren -If you have an exponent on the same bases, when you divide just subtract the exponents.  For example:Notice the base "x" must be the same!  If they are the same base, just subtract the exponents as shown above.Here is a numerical example:So the answer is 8.Hope that helps

Here is another example:   3^(-1) / 3^(-2) = 3^[(-1)-(-2)] = 3^[-1+2] = 3^1 = 3 Or try this one: 2^x / 2^2 = 2^2     Solve for x 2^(x-2) = 2^2 which can only be true if x-2 = 2 so x = 4.

Whenever you divide exponents, just subtract them.Example: x^12/x^6 = x^612 - 6 = 6
