$5 n^{- 3} = \frac{5}{n^{3}}$ $5n^-3 = 5/n^3$

Explanation:

Given: $5 n^{- 3}$ $5n^-3$ is an expression with a negative exponent.

When any value has a negative exponent it means we are looking at the reciprocal of a fraction. To evaluate the reciprocal we need to divide $1$ $1$ by the value and change the exponent to positive.

$5 n^{- 3} = 5 (n^{- 3}) = 5 (\frac{1}{n^{3}}) = \frac{5}{n^{3}}$ $5n^-3 = 5(n^-3) = 5(1/n^3) = 5/n^3$
