Answer 49

?

Answer 50

@Loujoelou eh......... please explain

Answer 51

\[\sqrt{169}-\sqrt{50}-\sqrt{8}\]
square root of redical 169 is 13 ,
square root of 50 is 5redical2 and
square root of 8 is 2redical2 therefor
\[13-5\sqrt{2}-2\sqrt{2}\]
\[13-7\sqrt{2}\] is your answer.

Answer 52

Factors of 8= 2*2*2.

That is what we would do. That would then give us \[2x \sqrt{2x}\]
