3√[24x^5 y^3]
3 is the index (the small number in top of the radical sign)
Please help me I do Appreciate it
$\displaystyle \sqrt[3]{24x^5y^3}=(24x^5y^3)^\frac{1}{3}=24^\frac{1}{3}(x ^5)^\frac{1}{3}(y^3)^\frac{1}{3}$ now there's an exponent rule that says to multiply powers together when you have powers raised to powers so that becomes $\displaystyle 2\sqrt[3]{3}x^\frac{5}{3}y$ or $\displaystyle 2y(3x^5)^\frac{1}{3}$
