Question

1/√3+√2-2/√5-√3-3/√2-√5

Answer 1

Hello mate!

1/ ( √3 + √2 ) = 1/( √3 + √2 ) × ( √3 - √2 )/( √3 - √2 )

= ( √3 - √2 )/( 3 - 2 ) = √3 - √2

2/( √5 - √3 ) =

2/( √5 - √3 ) × ( √5 + √3 )/( √5 + √3 )

= 2( √5 + √3 )/ ( 5 - 3 ) = √5 + √3

3/( √2 - √5 ) =

3/( √2 - √5 ) × ( √2 + √5 )/( √2 + √5 )

= 3( √2 + √5 )/( 2 - 5 ) = - √2 - √5

√3 - √2 - ( √5 + √3 ) - ( - √2 - √5 )

= √3 - √2 - √5 - √3 + √2 + √5

= 0

Hope it helps
