what is the cube root of 56?

56

2 x 28

2x2x14

2x2x2x7

2 * cubic root(7)

Sorry....didn't know what you needed

C'mon,   use the calculator to get   

3.8258623

I need it in radical form

Cube root*56 becomes cube root*7x8.

You then move the 8 out of the cube root, changing it into its cube root, 2cube root*7.

Mixed radical 2cube root*7
