**Ms. Sue**, Monday, April 13, 2009 at 9:07pmI don't know exactly what a systematic trial is here -- but it seems to me that you simply find the square root of these numbers and then round to the nearest hundredth.

Example:

square root of 20 = 4.472 = 4.47

**Ryan**, Monday, April 13, 2009 at 9:33pmexactly what Ms. Sue said square root of 20 is 4.472135 round that to 4.47. What perfect square is closest to 20. Like 4 squared is 16, 5 squared is 25. 16 IS CLOSER SO it will be more likely closer to 4 than 5 i dk if you are talking about this. Also think about your decimals, if you know it is not a perfect square think of a decimal which will multiply or square and give you a number which you will know when you add to four, the whole answer will be 20
