Question

how to solve
$\sqrt{800}$
​

Answer 1

Answer:

$20 \sqrt{2}$

Step-by-step explanation:

$\sqrt{800} = \sqrt{8 \times 100} \\ = 10 \sqrt{8} \\ = 10 \sqrt{2 \times 4} \\ = 10 \times 2 \sqrt{2} \\ 20 \sqrt{2}$

Note:

For further calculation,

$\sqrt{2} = 1.414$

hence

$20 \sqrt{2} = 20 + \times 1.414 \\ = 28.284$
