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
