Using only two 2s and any mathematical symbols, make 5. NO TRICKS

Good Luck

that is four 2s. Only TWO 2s.

2 + 2 = 5!

Nope. There's a solution. No tricks.

No it does not!

Give up yet?

I'll post the solution tomorrow to give everyone time to think about it.

2+2+1=5...

2x2.5=5...

2.5+2.5-5...

√(.2 ^ -2)

If any mathematical symbol, you could just use the 5th element of Z. So something like A sub n where n is an element of Z for n = 5. Perhaps you just use 5, considering you said any symbol. Or the 6th element of the fibonacci sequence, which can be represented by a symbol. Or N, where n happens to equal 5. Or something which is any operation with 2 twos that is strictly increasing and have it continue until it reaches our desired ceiling of 5. We might only need 2 twos to represent what we mean, but it would be done ad infinitum to reach 5.
