Question

what is complex number​

Answer 1

Step-by-step explanation:

A complex number is a number that can be expressed in the form a + b i, where a and b are real numbers, and i represents the “imaginary unit”, satisfying the equation {\displaystyle i^{2}=-1\;.} Because no real number satisfies this equation, i is called an imaginary number.

Answer 2

Answer:

A complex number is any number that includes i. Thus, 3i, 2 + 5.4i, and –πi are all complex numbers. (In fact, the real numbers are a subset of the complex numbers-any real number r can be written as r + 0i, which is a complex representation.)
