Answer:

The value of x is [tex]2\sqrt[3]{2}[/tex]

Step-by-step explanation:

We are given [tex]2+x^3=18[/tex]

We need to solve for x

First we subtract 2 both sides

[tex]x^3=18-2=16[/tex]

Taking cube roots both sides to isolate x

[tex]x=\sqrt[3]{16}[/tex]

Simplify the radical

[tex]x=2\sqrt[3]{2}[/tex]

Thus, The value of x is [tex]2\sqrt[3]{2}[/tex]
