How to square root the imaginary part??

If your calculator can compute the imaginary part then ur are lucky, if not we have to use this method to find the answer.

for example  √(5+3j) = convert  into polar form which is 5.83e^30.96
and then, by using this equation

(√5.83)(cos(30.96/2) - jsin(30.96/2)) = convert into polar form then ur got the answer.

* angle need to divide by (2 )..
