How to find the x value of 2x^3-27

Answer 1

x = 3∛(3) / ∛(2).

Explanation:

Start by adding 27 to both sides of the equation to isolate the term with x^3 on the left side:

2x^3 = 27

Next, divide both sides by 2 to solve for x^3:

x^3 = 27 / 2

Now, take the cube root of both sides to find the value of x:

x = ∛(27 / 2)

x = ∛(27) / ∛(2)

Simplify the cube root of 27:

x = 3∛(3) / ∛(2)

So, the x-values for which 2x^3 - 27 equals zero are x = 3∛(3) / ∛(2).
