Question

what is the form of complex no

Answer 1

No. Can be divided into two parts.
(1) Real no.
(2) complex no.

The real number a is called the real part of the complex number a + bi; the real number b is called the imaginary part of a + bi.

A complex number is a number of the form a + bi, where a and b are real numbers and i is an indeterminate satisfying i2 = −1. For example, 2 + 3i is a complex number.
