Question

Estimate each of these square roots.

a) √80
b) √27
c) √110
d) √0.03
e) √0.12

Answer 1

a) √80 ≈ 9

b) √27 ≈ 5

c) √110 ≈ 10

d) √0.03 ≈ 0.2

e) √0.12 ≈ 0.3

Explanation:

a) √80

80 is close to 81

Therefore, √80 can be estimated as √81

√81 = 9

`\Large\boxed{√(80)\approx9 }`

b) √27

27 is close to 25

Therefore, √27 can be estimated as √25

√25 = 5

`\Large\boxed{√(27)\approx5 }`

c) √110

110 is close to 100

Therefore, √110 can be estimated as √100

√100 = 10

`\Large\boxed{√(110)\approx10 }`

d) √0.03

0.03 is close to 0.04

Therefore, √0.03 can be estimated as √0.04

√0.04 = 0.2

`\Large\boxed{√(0.03)\approx0.2 }`

e) √0.12

0.12 is close to 0.09

Therefore, √0.12 can be estimated as √0.09

√0.09 = 0.3

`\Large\boxed{√(0.12)\approx0.3 }`

Hope this helps!! :)
