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
Express in the standard form a+i b:
1-3 i
1+ 3 i
-1-3 i
The additive inverse of 1 - i is
0 + 0i
-1 + i
The conjugate of a complex number is . Then, that complex number is
If Z1=2 + i, Z2 = 3 - 2 i and Z3 = -1/2 + √3/2 then the conjugate of z1z2 is
i
8 + i
8 - i
6 - i
If , then is (where is complex conjugate of z).
2 (1 + i)
(1+i)
If (3+i) z = (3-i) , then the complex number z is.
a (3-i), a∈R
, a∈R

Express in the standard form a+i b: ((-3+i) (4-2 i)
10+10 i
-10 -10 i
-10 + 10 i
If z is a complex number such that Re(z) = Im (z) , then
Re (Z2) = 0
Im (z2) = 0
Re (z2) = Im (z2)
z2 = 0
