​

Answer 1

Answer:

$23 \sqrt{2 }$

Answer 2

Answer:

The value is 32.522.

Step-by-step explanation:

The expression is:

$\sqrt{72}+\sqrt{800}-\sqrt{18}$

Simplify as follows:

$\sqrt{72}+\sqrt{800}-\sqrt{18}=6\sqrt{2}+20\sqrt{2}-3\sqrt{2}\\=23\sqrt{2}\\=23\times1.414\\=32.522$

Thus, the value is 32.522.
