To estimate: Square root

Answer to Problem 66SR
Estimated value of
Explanation of Solution
Given information: A square root number
Concept used : It is to fine two perfect square numbers in between those, the number 54 lies and square root of its closest that perfect square number becomes the estimated value of square root of 54.
Calculation: As 54 lies between two perfect square numbers 49 and 64, so that 49 is square of 7 and 64 is square of 8, and also 54 is closest to 49, thus, value of
Or,
Conclusion: By above concept, it is cleared that as 54 is more closer to perfect square 49, its square root value -7 will also be the value of
