(a ^ m)/(a ^ n) = a ^ (m - n) Use the rules of exponents to simplify each expression.

To simplify the expression, we can use the rule of exponents, which states that when we have a division of two numbers with the same base, we subtract the exponents.

So, (a^m) / (a^n) = a^(m-n)

In this case, (a^m) / (a^n) = a^(m - n)

Therefore, we can simplify the expression as a^(m - n).
