y^1/4=2. Solve for y.

Question

It is y to the 1/4 power = 2. It says y=16. How is that, what are the steps?

Answer 1

y^(1/4) = 2

 

To try and find the value of 'y' you can multiply both sides of the equation to the power of 4:

(y^(1/4))^4 = (2)^4

y^(4/4) = (2)^4

y^1 = (2)^4

y = 2×2×2×2

y = 4×4

y = 16   

Hope this helps .
