Question

How do you find the complex conjugate of number `-1 + 2sqrt2i`?

Answer 1

Complex conjugate of `-1+2sqrt2i` is `-1-2sqrt2i`

Explanation:

Complex conjugate of any complexnumber `a+bi` is `a-bi`. In facct they are conjugate off each other. This means the sign of imaginary part changes from plus to minus or minus to plus.

Hence, complex conjugate of `-1+2sqrt2i` is `-1-2sqrt2i`
