For any complex number z, |z| is equal to
If z₁ and z₂ are any two complex numbers, then
If z = 3i - 4 , then z+ overline z =
If n is an even integer, then (i)" is equal to:
If z is any real number x, then its conjugate is:
If z = (0, 1), then z² is:
The product of two conjugate complex numbers is:
Real part of (2 + i)/i is equal to:
The plane on which complex numbers are reprsented is called:
The modulus of a complex number z = x + iy is the distance of P(x,y) from:
If z₁ = 2 + 3i, z₂ = 1 − i, then |z₁ × z₂| is:
If |x + 5i| = 3, then x is equal to:
Multiplicative inverse of (3,4) is:
