Answer 2

Answer:

Answer:A complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i satisfies the equation i² = −1. Because no real number satisfies this equation, i is called an imaginary number. For the complex number a + bi, a is called the real part, and b is called the imaginary part.
