plz mark as BRIANLIEST

Step-by-step explanation:

20 sq root 2/ sq. root 11-1

multiply both numerator and denominator with sq.root 11 +1

(20 sq. root 2 * sq.root 11 +1)/(sq.root 11-1 * sq.root 11 +1)

(20(sq.root22+sq.root 2)/(11-1))

A^2- B^2 = (A+B)(A-B)

so answer is

2(sq.root 22+ sq. root 2)
