WebTo solve a division of complex numbers, we have to multiply both the numerator and the denominator by the conjugate of the denominator. Recall that the conjugate of a complex number is obtained by changing the middle sign of the original complex number. We can solve the division \frac {4+5i} {2-3i} 2−3i4+5i in the following way: WebTo divide complex numbers, we have to start by writing the problem in fractional form. Then, we have to multiply both the numerator and denominator by the conjugate of the denominator. Remember that to find the conjugate of the denominator, we simply have to change the sign to the imaginary component. For example, the conjugate of a+bi a+ bi is ...

WebNov 17, 2024 · This is an example of a complex number: 3 + 4i. It means take 3 and add 4 times i. The letter i is the symbol for the square root of -1 or √ (-1). In other words, the complex number 3 + 4i means 3 plus the quantity 4 times the square root of -1. A complex number has two parts: an ordinary part and a part that includes the letter i. WebThe reason for getting rid of the complex parts of the equation in the denominator is because its not easy to divide by complex numbers, so to make it a real number, which is a whole lot easier to divide by, we have to multiply it by a number that will get rid of all the imaginary numbers, and a good number to use is the conjugate.
