${(- 216 \times 729)}^{\frac{1}{3}} = - 54$ $(-216xx729)^(1/3)=-54$

Explanation:

${(- 216 \times 729)}^{\frac{1}{3}}$ $(-216xx729)^(1/3)$

${(a b)}^{m} = a^{m} \times b^{m}$ $(ab)^m=a^mxxb^m$

${(- 216 \times 729)}^{\frac{1}{3}} = - 6 \times 9$ $(-216xx729)^(1/3)=-6xx9$

$a = - 216, a^{\frac{1}{3}} = - 6$ $a=-216, a^(1/3)=-6$

$b = 729, b^{\frac{1}{3}} = 9$ $b=729, b^(1/3)=9$

${(- 216 \times 729)}^{\frac{1}{3}} = - 54$ $(-216xx729)^(1/3)=-54$
