Can Excel Solve for y in a Power 4 Equation?

[edmondng]

I tried TI89 and it did not work

Trying to solve for y in the following equation. I don't have a lot of software resource available to me so no matlab/mathematica/mathcad etc
I'm going try in excel if it can do it.

-383^(4-y) + 408^(4-y) + 297^(4-y) - 301^(4-y) = 3.358*10^10Thanks

edit: did anyone get y = -0.283068? TI work but said multiple solution may exist

Maple gives y = -.2822793449
