Answer 2

The value of expression is:

`56√(10)`

Explanation:

We are asked to simplify the following expression:

product of Seven square root eight times four square root five.

i.e. Mathematically this expression is represented by:

`7√(8)* 4√(5)`

`=7* 4* √(8)* √(5)\\\\=28* √(8)* √(5)`

Also we know that:

`√(a)* √(b)=√(ab)`

Hence,

`√(8)* √(5)=√(40)=2√(10)`

Hence, The value of expression is:

`7√(8)* 4√(5)=56√(10)`
