I need help with 1-4 plz will mark you theEST REALLY HELP THNX

See below.

Step-by-step explanation:

1. sqrt(8)

2^2 = 4; 3^2 = 9

sqrt(8) is between 2 and 3, but it is closer to 3 than to 2.

2.7^2 = 7.29 too low

2.8^2 = 7.84 too low

2.9^2 = 8.41 too high

sqrt(8) is between 2.8 and 2.9

2.8 and 2.9

2. sqrt(14)

3^2 = 9; 4^2 = 16

sqrt(14) is between 3 and 4, but it is closer to 4 than to 3.

3.7^2 = 13.69 too low

3.8^2 = 14.44 too high

sqrt(14) is between 3.7 and 3.8

3.7 and 3.8

3. sqrt(20)

4^2 = 16; 5^2 = 25

sqrt(20) is between 4 and 5

4.3^2 = 18.49 too low

4.4^2 = 19.36 too low

4.5^2 = 20.25 too high

sqrt(20) is between 4.4 and 4.5

4.4 and 4.5

4. sqrt(66)

8^2 = 64; 9^2 = 81

sqrt(64) is between 8 and 9, but it is closer to 8 than to 9.

8.0^2 = 64 too low

8.1^2 = 65.61 too low

8.2^2 = 67.24 too high

sqrt(66) is between 8.1 and 8.2

8.1 and 8.2
