Question

what is 8+the square root of 13?

Answer 1

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

Answer 2

use your calculator =o

Answer 3

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

Answer 4

@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? ;-)

Answer 5

square roots i mean so

\[\sqrt 9 < \sqrt 13 < \sqrt 16\]
\[3<\sqrt 13 <4\]

Answer 6

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

Answer 7

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

Answer 8

;-) 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.
