A negative exponent in the denominator (bottom) of a fraction is like having a positive exponent in the fraction's numerator. So 1/[x^(-2)] will be rewritten as x^2.

Answer by  esteban (1334)

A negative exponent tells us to take the reciprocal. So, when there is a base with a negative exponent in the denominator, you just need to move that base to the numerator and switch the exponent back to positive. Here's an example: 5/(4^-3) = 5 * 4^3. The negative exponent causes the base to switch positions.

You solve a fraction with a negative exponent in the denominator by subtracting the exponent in the denominator from that of the numerator.
