Answer 1

Solution :-

(1)

We know that z= x+iy conjugate of z is

x-iy

So ,( -2)+ 3i let's assume (-2) = x and 3 = y

it's conjugate will be x-iy so (-2)-(3i)

= -2 -3i Answer

(2) (1+i)²

we know (a+b)² = a²+b² +2ab

so , 1²+(i)² +2*(1)*(i)

=> 1 -1 +2i

=> 0 +2i

where x = 0 and y = 2

it is in form of x+iy so it's conjugate will x-iy

so. 0-2i = -2i will be it's conjugate .
