Question

can the cubed root of 15x^2, over 3 be simplified any more. (original problem: cubed root of 5/3x) the directions were to rationalize the denominator of each expression.

Thankss!!!!!

Answer 1

since you have (5/3x)^1/3, you want to multiply by (3x)^2/3 top and bottom, giving

(5*9x^2)^1/3 / 3x
or,
cbrt(45x^2)/3x
