10. Find the two perfect squares that 27 lies between. Find the two integers that lies between. Estimate to the nearest tenth. Try 5.2: 5.2 2 = 27.04Too high, try 5.1. Too low 5.1 2 = 26.01 Check On a calculator ≈ 5.1961524 ≈ 5.1 rounded to the nearest tenth. < < 5 < < 6 Because 27 is closer to 25 than to 36, is close to 5 than to 6. Because 27 is closer to 27.04 than 26.01, is closer to 5.2 than to 5.1. Example 1: Estimating Square Roots
