To estimate: The square root

Answer to Problem 64SR
Estimated value of
Explanation of Solution
Given information: A square root
Concept used: It is to find two perfect square numbers in between those, the number 79 lies and square root of its closest that perfect square number becomes the estimated value of square root of 79.
Calculation: As 79 lies between two perfect square numbers 64 and 81, so that 64 is square of 8 and 81 is square of 9, and also 79 is closest to 81, thus, value of
Conclusion: Thus, by above concept, it is cleared that as 79 is close to perfect square 81, its square root value 9 will also be the value of
