WebJan 10, 2016 · Explanation: 4 + 5i 2 − 3i. Whenever we divide complex numbers we multiply both numerator and denominator with the complex conjugate of the denominator, this makes the denominator a real number. If the complex number is a + ib then the complex conjugate is a − ib. For example. (a +ib)(a − ib) = (a)2 − (ib)2. = a2 −i2b2. WebFor example, any common divisor of $11+7i$ and $18-i$ must divide any linear combination of them, such as $1\cdot(11+7i)+7\cdot (18-i)$. This is $137$. So any common divisor must divide the norm of $11+7i$, which is $170$, and must also divide $137$. These numbers are relatively prime in the ordinary sense, so they are also relatively prime in ...

How do you divide #(4+5i)/(2-3i)#? - Socratic.org
WebWhen multiplying a number by its conjugate you should end up with a real number. You can check which 2 complex numbers, multiplied, give you a real number. Let's start with your school's answer. If you do (7-5i)* (-7+5i), you get 49 +70i-25i^2. This, in simplified form, is equal to 74+70i, which is a complex number, not a real number.
