Believes in practical knowledge rather than theoretic concepts of the subjects..

well equate z=5+4i with (a+bi)^2 step1- (a+bi)^2=5+4i now expanding (a+bi)^2 we will get a^2+2abi-b^2=5+4i now in the next step--- (a^2-b^2) is a real part and 2abi is a complex part so equate it from the right side.. u will get (a^2-b^2)=5---(1) and 2abi=4i--(2) put the value of a=4/2b...
