WitrynaA 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 polynomial with real coefficients in the single indeterminate i, for which the relation i 2 + 1 = 0 is imposed. Based on this … Witryna17 lip 2024 · Solution. a + b i. Remember that a complex number has the form a + b i. You need to figure out what a and b need to be. a − 3 i. Since − 3 i is an imaginary number, it is the imaginary part ( b i) of the complex number a + b i. This imaginary number has no real parts, so the value of a is 0. 0 − 3 i.
