$\frac{4 s^{2}}{s^{- 7}}$

Step 1

Move $s^{- 7}$ to the numerator using the negative exponent rule $\frac{1}{b^{- n}} = b^{n}$ .

$4 s^{2} s^{7}$

Step 2

Multiply $s^{2}$ by $s^{7}$ by adding the exponents.

$4 (s^{7} s^{2})$

Step 2.2

Use the power rule $a^{m} a^{n} = a^{m + n}$ to combine exponents.

$4 s^{7 + 2}$

Step 2.3

Add $7$ and $2$ .
