Cube of 3x - 81 = 0, find X It's three times (the cube of x)

3x^3-81=0
x^3=27
x=3

The third power of 3x + 81 / 125 = 0 solves the equation x =?

The solution is 3x ^ 3 + 81 / 125 = 0
That is 3x ^ 3 = - 81 / 125
That is, x ^ 3 = - 27 / 125
That is, x ^ 3 = (- 3 / 5) ^ 3
So the solution is x = - 3 / 5

The cube of 3x is negative 81. Find the value of X,

3x³=81
x³=27
x=3
