If (3+i) z = (3-i) , then the complex number z is.
a (3-i), a∈R
, a∈R
a(3+i), a∈R
a (-3 + ), a∈R
Write real and imaginary parts of 3/2 i
Re(Z) = 3 Im(Z) = 2 i
Re(Z) = 0 Im (Z) = 3/2
Re(Z) = 3 i Im (Z) = 2
None of these
If Z is a complex number such that , then
z is purely real
z is purely imaginary
z is any complex number
real part of z is the same as its imaginary part
The additive inverse of 1 - i is
0 + 0i
-1 + i
If Z1 = √2 ( cos π/4) and z2 = √3 (cos π/3 + i sin π/3 ) then |z1z2| is
