Question

Please can I have some help with these questions for my homework.

Answer 1

Answer:

The answer is

1) 2

2) 5$\sqrt{11}$

Step-by-step 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}
