Question

What is (the square root of 7)- 5/(the square root of 2) + 5?

Answer 1

`=> -(26 + sqrt14 - 5sqrt2 - 5sqrt7 )/23`

Explanation:

`(sqrt7 - 5) / (sqrt2 + 5)`

`=> ((sqrt7 - 5)(sqrt2 - 5)) / ((sqrt2 + 5) (sqrt2 - 5))`

`=> (sqrt14 - 5sqrt2 - 5sqrt7 + 25) / (2 - 25)`

`=> -(26 + sqrt14 - 5sqrt2 - 5sqrt7 )/23`
