How do you find the square root of 72? - Answers

To find the most exact answer, you have to use the calculator. If not you can try out by yourself. First, find the nearest perfect squares. For example, the nearest perfect squares are 64(8x8) and 81(9x9). So you know that the answer is between 8 and 9.Now you are ready to began. First start with 1 decimal place like 8.1 .The answer(8.1x8.1) is too far away from 72. So try a higher decimal, say 8.4. Try the first decimal until you know roughly where the answer is between. For 72, it is between 8.4 and 8.5. So now you can take on two decimals.Repeat the same thing until you find the second decimal, and go on to the third decimal. Normally they will ask for two/ three decimal placing. Hope this helps and good luck!
