Use Euler's Formula to write 2sq.rt.2 -2isq.rt.2 in exponential form.

My answer: 4e^i(7pi/4)

I just need confirmation that my answer is correct. Thanks.

I redid the problem: Use Euler's formula to write 2sqrt(2)-2isqrt(2) in exponential form.

I was told by this forum that my answer 4e^i(7pi/4) is incorrect.

Is 4e^i(pi/4) the correct answer? If not, where am I making the error?
