If y to the power of y equals 8 what does y equal?

16. Because if y=8 then the question becomes 8+8. Which equals 16.

using normal algebraic methods, all I can get is m=0 and y=all numbers

There can be no answer.y = y is an identity - a statement that is true for all values of y.That leaves y = - 3 - x. It is not possible to solve one linear equation in two unknown variables (x and y)....

there's really no given answer.this kind of problem is usually answered by 'all whole numbers' or something like that because 'x' directly infulences the 'y' so, as i stated before, no real given...

Sorry, but it is impossible to solve this equation by itself. Since you have two unknowns, you need two equation.
