(1) 59.03
(2) 3.4158
(3) 34.158
(4) 720.5

Answer 1

(1) The value of the square root of 59.03 up to the second decimal place can be obtained by using the division method as follows:

$\Rightarrow \sqrt{59.03}=7.683$
∴ The value of the square root of 59.03 up to the second decimal place = 7.68

(2) The value of the square root of 3.4158 up to the second decimal place can be obtained by using the division method as follows:

$\Rightarrow \sqrt{3.4158}=1.848$
∴ The value of the square root of 3.4158 up to the second decimal place = 1.85

(3) The value of the square root of 34.158 up to the second decimal place can be obtained by using the division method as follows:

$\Rightarrow \sqrt{34.158}=5.844$
∴ The value of the square root of 34.158 up to the second decimal place = 5.84

(4) The value of the square root of 720.5 up to the second decimal place can be obtained by using the division method as follows:

$\Rightarrow \sqrt{720.5}=26.842$
∴ The value of the square root of 720.5 up to the second decimal place = 26.84
