Division of Complex Number with Square Root

[Dalmain]

Hi Everyone

Hope you are all well.

I've attached the problem, the text book shows the answer as 0.908 cis 25.453. So I've gotten the modulus correct but not the amplitude. Problem is I can't tell where I went wrong. Have worked it out a few times but keep getting the same answer.

Any help is always appreciated.

Can you, will you please tell us what textbook you are using?
It appears that what you have posted is not at all standard with respect to complex numbers.
