Question 114713
the cube root of {{{27}}}

you need to find a number whose cube is {{{27}}}

remember multiplication of number itself: 1*1*1 is equal to 1^3

 we can take number {{{3}}} and do the same: {{{3*3*3=3^3=27}}}

then you can write

{{{x = root(3,27)}}}

as


{{{x = root(3,3^3)}}}.........eliminate cube root and cube

{{{x = 3}}}
