The conjugate of a complex number a + bi (with real coefficients a, b) is what you get when you "replace" i with -i, namely a - bi. For example, the conjugate of i is -i, the "other" square root of -1.

hope this will help yuh dear

Answer 2

Answer:

Conjugate of any complex number

a+bi is a−bi

Step-by-step explanation:

A conjugate of a number is a number that goes with it in the sense that multiplying the two numbers together yields a simpler kind of number.

For numbers involving radicals, we want to find a multiplier that results in a rational result. For complex numbers we want to find a multiplier that lead to a real result.
