Answer 1

see explanation

Explanation:

(a)

consider the perfect squares either side of 90

these are 81 and 100 , then

`√(81)` <
`√(90)` <
`√(100)` , that is

9 <
`√(90)` < 10

`√(90)` is between 9 and 10

(b)

consider the perfect squares either side of 135

these are 121 and 144 , then

`√(121)` <
`√(135)` <
`√(144)` , that is

11 <
`√(135)` < 12

`√(135)` is between 11 and 12
