Estimate Square Root Calculator
- 1. Estimate Square Roots ● Also called find square root without a calculator ● Quick and dirty way to find an estimate (approximation) or a square root ● Find goalposts, or endpoints ● High Endpoint (h) ● Low Endpoint (l) ● Square Root is between l and h 1
- 2. Estimate Square Root Steps ● Estimate the square root of a number (n) ● Start at 1 and keep squaring integers. ● 12 = 1, 22 = 4, 32 = 9, ... ● Once the square of your integer is greater than n, Stop ● This is your high value, call it h. ● Take the last squared integer before h, this is your low value, call it l ● l < ⺁n < h 2
- 3. Estimate Square Root Example ● Estimate the square root of 40 ● Start at 1 and keep squaring integers ● 12 = 1, 22 = 4, 32 = 9, 42 = 16, 52 = 25, 62 = 36, 72 = 49 ● 49 is your high value, call it h. ● 36 is our l value ● 36 < ⺁40 < 49 3
