((1(1+i)-2(1-4i))/((1-4i)(1+i))*((3-4i)/(5+i))
((1+i-2+8i)/(1+i-4i-4i^2))*((3-4i)/(5+i))
i^2=-1

Let z1= x+iy --(1)
z2=a+ib --(2)
Rez1=x --(3) Imz1=y --(5)
Rez2=a --(4) Imz2=b --(6)
From (1&2) z1z2=(x+iy)(a+ib)
=xa+ixb+iya+i^2yb. (i^2=-1)
= xa+ixb+iya-yb
=xa-yb + i(xb+ya)
Re(z1z2)= xa-yb -- LHS
from(3,4,5&6)
Rez1Rez2-Imz1Imz2 = xa-yb --- RHS
LHS = RHS .Hence Proved.
