Square Root Of 85

What if you don't have a calculator?

81 <85 <100.

9 2 <85 <10 2.

So you know that the square root of 85 is between 9 and 10 and is close to 9 (because 85 is close to 100 to 81).

So, trial and error ... since you only need a tenth, you need to use 9.1 and move on. (Since 85 is very close to 81, I think it's very low.)

(9.1) 2 = (9.1) (9.1) = 82.81.

(9.2) 2 = 84.64.

9.2 is close to 85 in my opinion.
