Multiplying complex numbers with square roots
WebA complex number is the sum of a real number and an imaginary number. A complex number is expressed in standard form when written \,a+bi\, where \,a\, is the real part and \,b\, is the imaginary part. For example, \,5+2i\, is a complex number. So, too, is \,3+4i\sqrt {3}. Imaginary numbers differ from real numbers in that a squared imaginary ...
