# What is the conjugate of 10-5i?

Jul 30, 2015

#### Answer:

$10 + 5 i$

#### Explanation:

To form the complex conjugate, simply replace all instances of $i$ with $- i$ and $- i$ with $i$.

For example, the complex conjugate of $\frac{\sqrt{3 + i}}{\sqrt[3]{3} i - 7}$ is $\frac{\sqrt{3 - i}}{- \sqrt[3]{3} i - 7}$
