(0!+0!+0!+0!+0!)^2 = 25

Am I allowed to use "^2"(square) here?

I missed the parenthesis that he wrote too, originally. But here is what he has cleaned up,

(0!+0!+0!+0!) +0!

I resurrected this topic because it is missing a couple of key other solutions.

The solution given so far is: (0! + 0! + 0! + 0!)! + 0! = 25

((0! + 0!)(0! + 0!))! + 0! = 25

((0! + 0!)^(0! + 0!))! + 0! = 25

- - - - - - - - - - - - - - - - - - - - - - - - -

Also, I am prepared to type other solutions in this thread that make use

of the square root, floor, and ceiling functions to achieve the value of 25.
