1. ## 3-4j sqaure roots

find the square roots of 3-4j

i used a software prog for the method, just want to check if it right?

-4j+3=0
-4j=-3

Do you understand that 3 - 4j is a complex number and your job is to find two other complex numbers of the form $a + jb$ (where a and b are real) such that $(a + jb)^2 = 3 - 4j$?

Note for the uninitiated: j is the symbol for $\sqrt{-1}$ used by electrical engineers.
