Answer 1

you know the square of 11 is 121 and that symbol means square root and square root of 121 is 11

Answer 2

b)11

since 11^2 is 11*11 = 12

and when you take the square root of 121

we get 11

(in b- √11^2) , it cancels out the square

square root cancels square since they perform opposite functions
