= ![2-\sqrt{(-1)(7)^2}](/tpl/images/0801/7025/4f355.png)
=![2-7\sqrt{-1}](/tpl/images/0801/7025/d2fcb.png)
=![2-7i](/tpl/images/0801/7025/1b45b.png)
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.

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