Math (Simplest Radical Form)
posted by Rayyan .
How do you figure out simplest radical form with variables and/or exponents and/or numbers outside the square root

if taking nth roots, look for nth powers and take them out of the radical, since the nthroot of x^n = x
example:
√300 = √100√3 = 10√3
∛640 = ∛64∛10 = 4∛10
∜80 = ∜16∜5 = 2∜5 
What is the 9th root of 64, in simplest radical form?
