how do i simplify the folowing radicals cuberoot of 54, 4root of 80, cuberoot of 125x^12 (is their a program?

Question

HELPPP

Answer 1

Look

³√54 = ³√(3³.2) = ³√3³ ³√2 = 3 ³√2

4root of 80 = 4root of [(2^4).5] = 2.[4root of 5]

cuberoot of 125x^12 = cuberoot of 5³ . x^12 = 5 x^(12/3) = 5x^4

Answer 2

54 = 27 x 2 cuberoot of 54 = 3 cuberoot of 2
80 = 16 x 5 4root of 80 = 2 4root of 5
cuberoot of 125x^12 = 5x^4

You don't need program, you just need to know you X table well.

Answer 3

1) 3* cube root of 2
2) 2 *4th root of 5
3) 5 x^4
