$\sqrt[3]{\frac{-64}{343}}$
✓
Answer
$\sqrt[3]{\frac{-64}{343}}$
$=\frac{\sqrt[3]{-64}}{\sqrt[3]{343}}$
$=\frac{\sqrt[3]{(-4)\times(-4)\times(-4)}}{\sqrt[3]{7\times7\times7}}$
$=\frac{-4}{7}$
$=\frac{\sqrt[3]{-64}}{\sqrt[3]{343}}$
$=\frac{\sqrt[3]{(-4)\times(-4)\times(-4)}}{\sqrt[3]{7\times7\times7}}$
$=\frac{-4}{7}$
