Step 2.1

Move $m^{- 3}$ .

$5 \cdot 2 (m^{- 3} m^{- 2})$

Step 2.2

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

$5 \cdot 2 m^{- 3 - 2}$

Step 2.3

Subtract $2$ from $- 3$ .

$5 \cdot 2 m^{- 5}$

Step 3

Multiply $5$ by $2$ .

$10 m^{- 5}$

Step 4

Rewrite the expression using the negative exponent rule $b^{- n} = \frac{1}{b^{n}}$ .

$10 \frac{1}{m^{5}}$

Step 5

Combine $10$ and $\frac{1}{m^{5}}$ .

$\frac{10}{m^{5}}$
