In this worksheet, you have to give two whole numbers between which the given square roots lie.
It is possible to estimate the square root of a number by finding a square number either side of it. You must know your square numbers up to 144, or more if you are interested.
√92 lies between √81 (9) and √100 (10), but note that 92 is nearer to 100.
We can estimate √92 as approximately 9.6 but we know for sure that it lies between 9 and 10.
