Question

X^3-64=0 Solve the equation

Answer 1

X^3 - 64 = 0

We want to solve for x. Start by getting x by itself on one side.
We can do this by adding 64 to both sides of the equation.

x^3 = 64

Now, to get rid of the 3rd power that x is raised to, we can raise both sides to the 1/3 power

(x^3)^1/3 = 64^1/3

(x^3)^1/3 is the same as x 

So x = 64^(1/3) and 64^(1/3) = 4

So x = 4 :)
