Well, it's both: you're using a machine to compute an approximation.

Why isn't it exact? Most square roots (such as the square root of two) are Irrational Numbers, so their decimal representation requires an infinite number of digits. We humans have to have finite answers, hence we round off.

Q: Why do you say approximate rather than compute when finding square roots when using a calculator or spreadsheet?

Using a calculator or by trial and error which is 41

Finding a square root without a calculator can be done by guessing at the approximate "right" answer then adjusting the guess until the answer squared is close enough to 2 to meet your need. There is however a formal process (Described at Link) which gives the right answer to any degree of accuracy needed.

The fastest and surest way to do that is to have a calculator that has a fraction button. (a b/c)

=divide the number your finding the percentage of by 100 then times by the percent.==Simple==E.G.==28 percent of 54==54~100=0.54==0.54*28=15.12=

With a calculator this can be done by doing 420*1.11.Without a calculator, it is also very easy, and is done by finding 10% of 420 which is 420/10 which is 42. So 42 = 10% of 420. And 1% of 420 is 4.2. 1%+10%+100% = 4.2+42+420 =466.2.466.2Very basic.:)
