--------------

√5

= √20 / √5

= √4

= 2

Answer 2

The answer is

1) 2

2) 5
`√(11)`

Explanation:

1) =\frac{\sqrt{2}\sqrt{2}\sqrt{5}}{\sqrt{5}}

= =\frac{\sqrt{2}\sqrt{2}\sqrt{5}}{\sqrt{5}}

= 2

2) \sqrt{99}+\sqrt{44}

\sqrt{99}=3\sqrt{11}

and

\sqrt{44}=2\sqrt{11}

So

3\sqrt{11}+2\sqrt{11}

= 5\sqrt{11}
