Question

what is complex numbers​

Answer 1

Answer:

a complex number is a number that can be expressed in the form a + bi,

Answer 2

In mathematics, 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 a symbol called the imaginary unit, and satisfying the equation i² = −1. Because no real number satisfies this equation, i was called an imaginary number by René Descartes.

A complex number is the sum of a real number and an imaginary number. A complex number is expressed in standard form when written a + bi where a is the real part and bi is the imaginary part. For example, 5+2i 5 + 2 i is a complex number. So, too, is 3+4i√3 3 + 4 i 3 .
