WebBy taking multiples of this imaginary unit, we can create infinitely many more pure imaginary numbers. For example, 3i 3i, i\sqrt {5} i 5, and -12i −12i are all examples of pure imaginary numbers, or numbers of the form bi bi, where b b is a nonzero real number. WebA complex number is expressed in standard form when written a + bi where a is the real part and bi is the imaginary part. For example, [latex]5+2i[/latex] is a complex number. So, too, is [latex]3+4i\sqrt{3}[/latex]. Imaginary numbers are distinguished from real numbers because a squared imaginary number produces a negative real number. northern lights daylesford 2022
