Write Using Positive Exponents -8(x^-3y^4)^-5

$- 8 {(x^{- 3} y^{4})}^{- 5}$

Step 1

Move ${(x^{- 3} y^{4})}^{- 5}$ to the denominator in ${(x^{- 3} y^{4})}^{- 5}$ using the negative exponent rule $b^{- n} = \frac{1}{b^{n}}$ .

$\frac{1}{{(x^{- 3} y^{4})}^{5}}$

Step 2

Rewrite $- 8 {(x^{- 3} y^{4})}^{- 5}$ with positive exponents.

$- 8 \frac{1}{{(x^{- 3} y^{4})}^{5}}$
