s^-3

Simplify by changing to an expression with a positive exponent.

1/s^3

To simplify the expression s^-3, we can rewrite it using a positive exponent. The key idea is to recognize that a negative exponent means we need to take the reciprocal of the base raised to the positive exponent.

So, in this case, we can rewrite s^-3 as 1/s^3. We have taken the reciprocal of s^3 and changed the negative exponent to a positive exponent. This simplification helps us to understand the expression more easily.
