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<sup>a-2</sup> , which is the greatest common factor, out.
5a<sup>a-2</sup>(25x<sup>2</sup> + 4)
check my thinking.
In the second, muliply the numerator and denominator by x to the power of -y.
