how do you solve these problems

(5x)to the power of a+4(5x)to the power of a-2

3 to the power of 5 times xto the power of y+4 divided by 9 times x to the power of y

factor 5a

^{a-2} , which is the greatest common factor, out.

5a

^{a-2}(25x

^{2} + 4)

check my thinking.

In the second, muliply the numerator and denominator by x to the power of -y.
