Evaluate ((2x)^-2)/((3x)^-2)

$\frac{{(2 x)}^{- 2}}{{(3 x)}^{- 2}}$

Simplify the expression.

Move ${(2 x)}^{- 2}$ to the denominator using the negative exponent rule $b^{- n} = \frac{1}{b^{n}}$ .

$\frac{1}{{(3 x)}^{- 2} {(2 x)}^{2}}$

Move ${(3 x)}^{- 2}$ to the numerator using the negative exponent rule $\frac{1}{b^{- n}} = b^{n}$ .

$\frac{{(3 x)}^{2}}{{(2 x)}^{2}}$

Simplify the numerator.

Apply the product rule to $3 x$ .

$\frac{3^{2} x^{2}}{{(2 x)}^{2}}$

Raise $3$ to the power of $2$ .
