@Omair Siddique For these questions, always transform the base in the form of e^ln(x). This simple thought can be used for questions like i^i and (a+bi)^(c+di).

@Omair Siddique We know that e^ln(x)=x (I used e because I can't type logs with bases, but it works for any number, not just e), so we can rewrite the equation as the following:

2^i=(e^ln(2))^i=e^(i*ln(2))

We can use Euler's formula now, to determine the actual value. Euler's formula says that e^(ix)=cos(x)+i*sin(x).

cos(ln2)+isin(ln2)
