The solution is $4^3$ or $64$.

Work Step by Step

To get rid of the negative exponent, we use the negative exponent rule, which states that if we have a negative exponent in the denominator, we can move the exponent from the denominator to the numerator and change its sign from negative to positive. If we apply this rule, we get: $$4^3$$ We can simplify this expression even further by cubing $4$, which is $64$.
