Answer:
i = imaginary number
Complex numbers are expressed in a + bi.
The i stands for imaginary number, because no real number goes with this equation.
In Complex numbers are written in the form a + bi, i called as iota and represented for the imaginary number.
What is a complex number?
Complex numbers are helpful in finding the square root of negative numbers.
A complex number is the sum of a real number and an imaginary number.
The idea of a complex number has come by solving a quadratic equation that has root as negative under root.
If we solve x² + 1 = 0 ⇒ x = √(-1) which is called as iota(i).
The general form of a complex number is a + ib where first part a called real and the ib is called imaginary.
For example, 8 + i9 here part 8 called as real part, and i9 called as imaginary part.
Given that
a + bi here i is iota
bi = imaginary part.
i = √(-1) so it will be called an imaginary number.
