I have a question in solving a root of a complex number... Solve: Z^{2} = 3  4i and 2xy = 4 Roots **> OK... the 2 solutions for z shown are indicated as correct in the text,
but these are the onnly solutions given. Thanks for you assistance, 

Hi John, Back in the third line when you write the complex number z as z= x + yi there is an assumption that x any y are real. The roots of x^{2} + 1 are not real and hence do not give extra solutions to your problem. Harley
