tangare [24]

Answer:

See below

Step-by-step explanation:

<em>There is a formula for estimating square root of non-perfect square numbers</em>
<em>√(A²±B) = A ± B/2A</em>
<em>where A² is the nearest perfect square, B is the difference between the original number and the perfect square</em>

<u>Examples</u>

1) √75 = √(8²+11) = 8 + 11/(2*8) = 8 + 11/16 = 8.6875
2) √114 = √(11² - 7) = 11 - 7/(2*11) = 10.6818
