WebbTo multiply two complex numbers z1 = a + bi and z2 = c + di, use the formula: z1 * z2 = (ac - bd) + (ad + bc)i. What is a complex number? 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 the imaginary unit, which is defined as the square root of -1. WebbThe expression has no real answer. The symbol i is created to represent and is called an imaginary value. Since , i 2 = –1. Any expression that is a product of a real number with i is called a pure imaginary number.. Example 1. Simplify each of the following. (6 i)(4 i) . This last expression is commonly written as so that the i is not mistakenly written under the …

WebbImaginary numbers are based on the mathematical number i. i is defined to be − 1. From this 1 fact, we can derive a general formula for powers of i by looking at some examples. Table 1. Table 1 E x p r e s s i o n W o r k R e s u l t i 2 = i ⋅ i = − 1 ⋅ − 1 -1 i 3 = i 2 ⋅ i = − 1 ⋅ i -i i 4 = i 2 ⋅ i 2 − 1 ⋅ − 1 = 1.
