Complex number definition algebra
WebA complex number is a number of the form a + bi, where a and b are real numbers, and i is an indeterminate satisfying i 2 = −1.For example, 2 + 3i is a complex number. This way, a complex number is defined as a … WebThe real number a is written as a+0i a + 0 i in complex form. Similarly, any imaginary number can be expressed as a complex number. By making a =0 a = 0, any imaginary number bi b i can be written as 0+bi 0 + b i in complex form. Write 83.6 83.6 as a complex number. Write −3i − 3 i as a complex number.
