    Hi mr_quick,

    \sqrt[3]{24x^5y^3}=\sqrt[3]{2^3\cdot 3 \cdot x^3 \cdot x^2 \cdot y^3}=2xy \sqrt[3]{3x^2}

    \sqrt[3]{24x^5y^3}=(24x^5y^3)^\frac{1}{3}=24^\frac{1}{3}(x  ^5)^\frac{1}{3}(y^3)^\frac{1}{3} now there's an exponent rule that says to multiply powers together when you have powers raised to powers so that becomes 2\sqrt[3]{3}x^\frac{5}{3}y or 2y(3x^5)^\frac{1}{3}
