How do you find the conjugate of the complex number sqrt5/8 + 1/8i?

Dec 8, 2015

For any complex number $a + b i$, the complex conjugate of the number is $a - b i$ (which may also be written $a + \left(- b\right) i$.
So the complex conjugate of $\frac{\sqrt{5}}{8} + \frac{1}{8} i$
is $\frac{\sqrt{5}}{8} - \frac{1}{8} i$.
