X^9 = 5.08, solve for x.

I forget how to do this. I need to know how* this is done.

There is no simple method to solve this by hand, nor is there any simple decimal solution (generally, ninth roots are irrational).

So you need to use a calculator or math package, and enter (5.08)^(1/9)

The answer is approximately 1.197920498.

Take the ninth root of 5.08

Using a calculator:

ninth-root(5.08) = 1.198 (rounded)

x^9=5.08,
x=5.08^(1/9),
x=1.198.
Answer: 1.198.
