Step One
Bring z^(-5) to the numerator.
x^3y^2(x^2 y^3 z^(m + 5)) = x^5 * 5y^5 * z
Step Two
Remove the brackets on the left
x^(3 + 2) * y ^ (2 + 3) * z^(m + 5) = x^5 * y^5 * z
x^5 * y^5 * z^(m + 5) = x^5 * y^5 * z Divide by x^5 * y^5
z ^(m + 5) = z^1 Since the bases are the same, you can equate the powers.
m + 5 = 1 Subtract 5
m = 1 - 5
m = - 4 <<<< Answer
