Question

What are complex numbers. Give examples

Answer 1

Complex numbers
A complex number is a number that can be expressed in the form a + bi, where a and b are real numbers and i is the imaginary unit, satisfying the equation i2 = −1. In this expression, a is called the real part and b is the imaginary part of the complex number/example of complex number
A complex number is a number of the form a + bi, where a and b are real numbers and i is the imaginary unit, satisfying i2 = −1. For example, −3.5 + 2i is a complex number. ... A purely imaginary number bi is a complex number 0 + bi whose real part is zero.
