​

Answer 1

$( \sqrt{5} - {3})^{2} \\ 5 - 9 \\ = - 4 \\ when \: two \: under \: \\ roots \: are \: mutiplied \\ \: then \: the \: under \\ \: root \: gets \: removed \\ \: and \: the \: actual \\ \: no. \: comes \: out \:$

Answer 2

$$\begin{lgathered}( \sqrt{5} - {3})^{2} \\ 5 - 9 \\ = - 4 \\ when \: two \: under \: \\ roots \: are \: mutiplied \\ \: then \: the \: under \\ \: root \: gets \: removed \\ \: and \: the \: actual \\ \: no. \: comes \: out \:\end{lgathered}$$
