#### Answer

$4s^{3}$

#### Work Step by Step

1. Take the variable/value with the negative exponent and move it over to the other side of the fraction line. In this case, move the "$s^{-3}$" from the denominator to the numerator. At this point, you should have $\frac{8s^{3}}{2}$ Remember that when you move a negative exponent from the bottom to the top of a fraction, it becomes positive. 2. Now, just divide the numerator by the denominator and you should have your answer.
