Describe how you would estimate the square root of a number that is not a perfect square without using a calculator.
could you please explain this to me?
Say you had to estimate √87. I would find the closest perfect square below it, 81, and the closest perfect square above it, 100. So now I can set up a problem.
81 < 87 < 100
√81 < √87 < √100
9 < √87 < 10
Since 87 is closer to 81 than 100, it would make sense for √87 to be closer to 9 than 10. I would guess √87 is about 9.4.
For comparison's sake, √87 = 9.32737905
Wolfie, good explanation.
