(vi) We can find the square root up to three decimal places by using long division until we get four decimal places and then rounding it to three decimal places. Hence, the square root of 427 up to three decimal places is 20.664.
(vii) We can find the square root up to three decimal places by using long division until we get four decimal places and then rounding it to three decimal places. Hence, the square root of 1.7 up to three decimal places is 1.304.
(viii) We can find the square root up to three decimal places by using long division until we get four decimal places and then rounding it to three decimal places. Hence, the square root of 23.1 up to three decimal places is 4.806.
(ix) We can find the square root up to three decimal places by using long division until we get four decimal places and then rounding it to three decimal places. Hence, the square root of 2.5 up to three decimal places is 1.581.
(x) We can find the square root up to three decimal places by using long division until we get four decimal places and then rounding it to three decimal places. Hence, the square root of 237.615 up to three decimal places is 15.415.
(xi) We can find the square root up to three decimal places by using long division until we get four decimal places and then rounding it to three decimal places. Hence, the square root of 15.3215 up to three decimal places is 3.914.
(xii) We can find the square root up to three decimal places by using long division until we get four decimal places and then rounding it to three decimal places. Hence, the square root of 0.9 up to three decimal places is 0.949.
(xiii) We can find the square root up to three decimal places by using long division until we get four decimal places and then rounding it to three decimal places. Hence, the square root of 0.1 up to three decimal places is 0.316.
(xiv) We can find the square root up to three decimal places by using long division until we get four decimal places and then rounding it to three decimal places. Hence, the square root of 0.016 up to three decimal places is 0.126.
(xv) We can find the square root up to three decimal places by using long division until we get four decimal places and then rounding it to three decimal places. Hence, the square root of 0.00064 up to three decimal places is 0.025.
(xvi) We can find the square root up to three decimal places by using long division until we get four decimal places and then rounding it to three decimal places. Hence, the square root of 0.019 up to three decimal places is 0.138.
(xvii) We can find the square root up to four decimal places by expanding 7/8 to decimal form up to eight digits to the right of the decimal point as shown below:
7/8=0.87578=0.875
Hence, we have: So, the square root of 7/8 up to three decimal places is 0.935.
(xviii) We can find the square root up to four decimal places by expanding 5/12 to decimal form up to eight digits to the right of the decimal point as shown below: Hence, we have: So, the square root of 5/12 up to three decimal places is 0.645.
