Answer:The set of complex numbers is the set of all numbers of the form a I bi, where a and b are real numbers. In a * bi, a is called the real part and b is called the imaginary part. Two complex numbers a * bi and c f di are equal if and only if their real parts are equal (a : c) and their imaginary parts are equal (b : d).In a * bi, a is called the real part and b is called the imaginary part. Two
complex numbers a * bi and c f di are equal if and only if their real parts are
equal (a : c) and their imaginary parts are equal (b : d).If b : 0, then a * bi is
a real number.If b * 0, then a * bi is an imaginary number.
The form a * bi is the standard form of a complex numbeg but for convenience we use a few variations of that form. If either the real or imaginary part of a
complex number is 0, then that part is omitted
Step-by-step explanation:If a * bi and c * di are complex numbers, we define their sum, difference,
and product as follows.
(a + bi) + (c + di) : (a.| c) * (b + Ai
(a + bi) * (c + di): (a - c) + (b * d)i
(a + bi)(c + di) : (ac - bd) + (bc + afii
