Question

simply ( root 13 - root 6 ) ( root 13 - root 6)​

Answer 1

Hey mate

(√13-√11)/(√13+√11)+(√13+√11)/(√13-√11)

= [(√13-√11)²+(√13+√11)²]/[(√13+√11)(√13-√11)]

= { 2[ (√13)²+(√11)²]}/[ (√13 )² - ( √11 )² ]

= [ 2( 13 + 11 ) ] / ( 13 - 11 )

= [ 2 × 24 ]/ 2

= 24

(root 13- root 6) (root 13 - root6)

(root 13- root 6 )square

a=root 13,b=root 6

( a+b)square= (a) square-2ab+ (b)square

(root13)square- 2×root 13×root 6 +( root 6)square

13- 156+ 6
