Is it possible to get 1?

Number Theory Level 2

Is it possible to make the following equation true:

2 X 2 = 1

by modifying either expression by raising it to a power, taking its square root, changing ii to a fraction, using its factorial,etc.

However in any way possible it is not allowed to discard the number 2 from either expression.

One way to do it is: 2^0 * 2^0 = 1 as x^0 is always equal to 1
