## anonymous 3 years ago what is 8+the square root of 13?

1. anonymous

I don't understand the question. That expression is already in simplest form, what else do you want to do with it?

i mean you can technically estimate it by finding the closest roots

@Outkast3r09 , yes, to get a decimal approximation, a calculator is the best way. There are old iterative methods for finding square roots by hand, but why bother? ;-)

5. anonymous

square roots i mean so $\sqrt 9 < \sqrt 13 < \sqrt 16$ $3<\sqrt 13 <4$

some teachers don't allow calculators... imagine that lol

Yeah, that's a good way to get a quick mental estimate. I doubt that's what @ihatealgebrasomuch is asking for though.

;-) I happen to be one of those teachers who doesn't allow calculators, that's why I said the expression is already in simplest form.
