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]
