Question

explain the definition of real and complex number? if your is correct so I will really follow u ok​

Answer 1

$\huge{\boxed{\boxed{\colorbox{red}{ANSWER}}}}$

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

Answer 2

$\large\bf{\underline\green{☕︎Good \: Morning☕︎}}$

Complex numbers are the numbers which are expressed in the form of a+ib where ‘i’ is an imaginary number called iota and has the value of (√-1).

For example, 2+3i is a complex number, where 2 is a real number and 3i is an imaginary number.

Therefore, the combination of both the real number and imaginary number is a complex number.

Real numbers are simply the combination of rational and irrational numbers, in the number system. In general, all the arithmetic operations can be performed on these numbers and they can be represented in the number line, also.

At the same time, the imaginary numbers are the un-real numbers, which cannot be expressed in the number line and is commonly used to represent a complex number.
