How to solve imaginary number as denominator
WebA complex number is a number of the form a + b i where. a. a is the real part of the complex number. b. b is the imaginary part of the complex number. If b = 0, then a + b i is a real number. If a = 0 and b is not equal to 0, the complex number is called a pure imaginary number. An imaginary number is an even root of a negative number. WebThe multiplicitive inverse of any complex number a + b i is 1 a + b i . However, since i is a radical and in the denominator of a fraction, many teachers will ask you to rationalize the denominator. To rationalize the denominator just multiply by the complex conjugate of the original complex number (which is now in the denominator).
