Simplify -x^-4y^-4

$- x^{- 4} y^{- 4}$

Step 1

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

$- \frac{1}{x^{4}} y^{- 4}$

Step 2

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

$- \frac{1}{x^{4}} \cdot \frac{1}{y^{4}}$

Step 3

Multiply $\frac{1}{y^{4}}$ by $\frac{1}{x^{4}}$ .

$- \frac{1}{y^{4} x^{4}}$
