How do you simplify 3x^-3y^-8 with positive exponents?

Oct 16, 2016

$\frac{3}{{x}^{3} {y}^{8}}$

Explanation:

Consider the example of ${4}^{- 2}$ this is another way of writing
$\frac{1}{4} ^ 2$

Using the method in the example and just to make the connection for you: write the question as $\text{ } 3 \times {x}^{- 3} \times {y}^{- 8}$

This is the same as: $\text{ } 3 \times \frac{1}{x} ^ 3 \times \frac{1}{y} ^ 8$

This is the same as: $\text{ } \frac{3}{{x}^{3} {y}^{8}}$
