Simplify ((m^-3n^4)/(n^-2))^4

${(\frac{m^{- 3} n^{4}}{n^{- 2}})}^{4}$

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

${(\frac{n^{4}}{n^{- 2} m^{3}})}^{4}$

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

${(\frac{n^{4} n^{2}}{m^{3}})}^{4}$

Multiply $n^{4}$ by $n^{2}$ by adding the exponents.

Use the power rule $a^{m} a^{n} = a^{m + n}$ to combine exponents.

${(\frac{n^{4 + 2}}{m^{3}})}^{4}$

Add $4$ and $2$ .

${(\frac{n^{6}}{m^{3}})}^{4}$

Apply the product rule to $\frac{n^{6}}{m^{3}}$ .

$\frac{{(n^{6})}^{4}}{{(m^{3})}^{4}}$

Multiply the exponents in ${(n^{6})}^{4}$ .

Apply the power rule and multiply exponents, ${(a^{m})}^{n} = a^{m n}$ .
