*This is on the assumption that the equation is [tex] (2y)^{\frac{3}{2}} [/tex]
So firstly, you'll need to rewrite this as [tex] 2^\frac{3}{2}*y^\frac{3}{2} [/tex]
Next, remember the rule for exponents to radicals: "[tex] x^\frac{m}{n}=\sqrt[n]{x^m} [/tex] . Applying this rule to both would look like this: [tex] \sqrt{2^3}*\sqrt{y^3} [/tex]
Next, simplify 2^3: [tex] \sqrt{8}*\sqrt{y^3} [/tex]
Next, apply the product rule of radicals (√ab = √a*√b) to this expression, and your answer will be [tex] \sqrt{8y^3} [/tex]
