Write Using Positive Exponents 4r^-3*2r^2

$4 r^{- 3} \cdot 2 r^{2}$

Step 1

Move $r^{- 3}$ to the denominator in $r^{- 3}$ using the negative exponent rule $b^{- n} = \frac{1}{b^{n}}$ .

$\frac{1}{r^{3}}$

Step 2

Rewrite $4 r^{- 3} \cdot (2 r^{2})$ with positive exponents.

$4 \frac{1}{r^{3}} \cdot 2 r^{2}$
