Cancelling out a root function of y

Hi there,

I've got an equation and I need to find the value of . I've been able to get on it's own side of the equation but am stuck on the last steps. The left side of the equation is and I have then used the rule for powers to achieve but I don't know what I need to do now to both sides of the equation to get on it's own.

Many thanks.

I did think that the power of 4 would do it, but Mathcad isn't giving me on it's own.

I'm starting to think I may have made an error in Mathcad.

Would somebody please confirm if

Many thanks.

This is correct

A quick and easy way to check is to give y a value and check.

so

let y = 1000

put this in your calculator to check, and you should get 1000.
