I'm not sure I can reproduce your equation, so I'm going to answer generally:
When you have a negative exponent, then that means you take the reciprocal of what is raised to the exponent, and the exponent becomes positive. Some examples to clarify:
x-2 = 1/(x2)
1/(x-2) = x2
(x-2)/(y-3) = y3/x2 <=== since both x and y have negative exponents, we take the reciprocal of each.
(x-3)-3(y+3)2 = (y+3)2/(x - 3)3 <=== since (x-3) has a negative power and is in the numerator, it moved to the denominator
(2x/3 + 5)2 [1/(3x/5 - 4)-4 ]= (2x/3 + 5)2 (3x/5 - 4)4 <=== (3x/5 - 4) has a negative power in the denominator, so it moves to the numerator. No changes are made to the fractions within the parentheses.
Hope that helps you get started.
