find the square root of the complex number 1 + 2i?


Find the square root of the complex number 1+2i





I was trying this question many times, but I could not get it and I don't know where to start.



Actually after squaring the 1+2i I got 1+2i, and I also tried multiplying by 1+i. However I don't know the exact answer.



Thanks in advance
