How do you find the square root of 841?

Answer 1

Well, isn't that a happy little question! To find the square root of 841, you simply need to think of a number that, when multiplied by itself, equals 841. In this case, the square root of 841 is 29. Just like painting a beautiful landscape, sometimes all it takes is a little patience and gentle brushstrokes to reveal the hidden beauty beneath the surface.

Answer 2

I can do it with a pencil or a slide rule, but I prefer to use a small calculator. When I do that, I get an answer of 94.027 I know that can't be right, because 90 x 90 is 8,100. You always have to do a sanity-check on the answer you get to see whether it makes sense. There are two ways to get a garbage answer out ... put garbage in, or make a calculating error. In this case, I accidentally punched in '8841' instead of '841'. The square root of 841 is actually 29.
