1. The problem statement, all variables and given/known data

Use Euler's formula to write $2^{1-i}$ in the form a+ib.

3. The attempt at a solution

I know this has to be so simple because I could do this easy if the question was to write $e^{1-i}$ in the form a+ib using Euler's. So what I do not understand is how does 1-i being raised on 2 rather than e change what I need to do to solve it. Thank you.

2^(1-i)=(e^log(2))^(1-i)=e^(log(2)*(1-i)).
