Give the equivalent numerator if the denominator is x³y².

x³y²
 For this case, the first thing you should know is the properties of the exponents.
 Let's write the full fraction:
 (1) / (x ^ 3 * y ^ 2)
 We have that by power properties:
 (1) / (x ^ 3 * y ^ 2) = x ^ -3 * y ^ -2
 Therefore the equivalent numerator is:
 x ^ -3 * y ^ -2
 
 x ^ -3 * y ^ -2
