As for example the square root of 64 is 8 but the cube root of 64 is 4
The cube root of 64 is 4.4x4=1616x4=64
This can be broken into cube root( 64 * 1000) = cube root(64) * cube root(1000) which is 4 * 10 = 40
The square root of 16 is four. Four cubed is 4 x 4 x 4 = 64
Suppose x3 = -64 then x3 + 64 = 0So (x + 4)*(x2 - 4x + 16) = 0So x = 4 or x = 2 +/- 2i*sqrt(3) where i is the imaginary square root of -1.-4 * -4 * -4 = -64So cube root of -64 = -4
