Find the value of x

Question

x¹⁰ = 1.28

 

Find x

Answer 1

x¹⁰ = 1.28     Take the 10th root of both sides.   x = ¹⁰√1.28

 

x = 1.02499

 

Answer 2

x is the tenth root of 1.28 -- you may find this decimal number, approximately, by using a calculator.

 

 

Answer 3

Thanushki, how can we get rid of the exponent? Take the tenth root of both sides (or take both sides to the 1/10).

 

x = 1.28^1/10

 

I don't have a calculator with me to do that, but go for it!
