Nerdo, not helpful. 

 

x^3 = 64

 

Thus, you can take cubic roots on both sides:

 

A cubic root is bascially saying, cubic root of x, cubed, is x. 

 

Similar to square roots and squares but instead, 3.

 

The cubic root of 64 is 4, since 4^3 = 64.

 

For advanced calculations or at least stuff you can't or will have lots of difficulty doing, you can use a scientific calculator to calculate.

 

x^3 = 2804024. Can you solve that? I can't, if you can do that mentally or in a short amount of time, you're very good at this. 

 

For that ^^^ it's best to use a claculator.

And imaginary roots     -2 - 2 i sqrt3        - 2 +  2 i sqrt3
