Question

I need help evaluating this problem

Answer 1

Your answer should be 16/9

Answer 2

$\bf \left( \cfrac{64}{27} \right)^{\frac{2}{3}}\implies \left( \cfrac{4^3}{3^3} \right)^{\frac{2}{3}}\implies \left( \cfrac{4^{3\cdot \frac{2}{3}}}{3^{3\cdot \frac{2}{3}}} \right)\implies \cfrac{4^2}{3^2}\implies \cfrac{16}{9}$
