Answer 2

Answer:

The simplified form of given expression is 70.

Step-by-step explanation:

The given expression is

$5\sqrt{7}\times 2\sqrt{7}$

It can be written as

$5\sqrt{7}\times 2\sqrt{7}=5\times 2\times \sqrt{7}\times \sqrt{7}$

$5\sqrt{7}\times 2\sqrt{7}=10\times (\sqrt{7})^2$

$5\sqrt{7}\times 2\sqrt{7}=10\times 7$

$5\sqrt{7}\times 2\sqrt{7}=70$

Therefore the simplified form of given expression is 70.
