bi = imaginary part
a and b are the real numbers.

[Since,
]

Therefore, its a non real complex number.
2 -
= 
= 
=
This number is a Non real complex number.

= 18i
It's a non real complex number.
3 + 2i
It's a non real complex number.
-289
It's a purely real number.

= 4 + 32
= 36
It's a purely real number.
