If you dont already know i is the number mathmeticians use as the answer for the problem sqrt(-1)

But i was wondering if you could use it as an exponent. My thinking is that if you set x^i=4 then take the i root of both sides

x=i*sqrtroot(4) then square both sides x^2=-1*4 symplify, x^2=-4 take the sqare root of both sides x=2i. but i might be wrong. plz it is bugging me to know.
