I think this will help you.
It's an online calculator that shows you how to solve problems step by step.
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.
