Answer 2

7+√5 + 7+√5

= ( 7 + 7 ) + (√5 +√5 )

Take √5 common :

= 14 + √5 ( 1 + 1 )

= 14 + 2√5

= 2 ( 7 + √5 )

It is in detail and hence looks long but once u will learn it will take seconds to solve these questions .

Additional point is that u cannot add under root numbers which are difffrent like this . For example : √7 and √5 .

And their are many similar rules to add such numbers .
