Having trouble understanding the solution to the following question:
Put (√3+i)50 in exponential and cartesian form.
I know the answer cartesian form is:
2502+250√32i
And the exponential form is:
250e50π6i
But I don't know how to get there.
I know that i50=i4(12)+2=i2=−1. Is that somehow used in the process?
What form is it given in?
Answer
Use the fact that√3+i=2(√32+i2)=2(cos(π6)+isin(π6)),together with de Moivre's formula.
