Best ResponseYou've already chosen the best response.0To find the mean of something, you add the terms and then divide by the amount of them. So, they equal 10 and there are two of them. 10/2 = 5. The mean should be 5.

Best ResponseYou've already chosen the best response.0So would I do something like 2*square root of the product?

Best ResponseYou've already chosen the best response.1Nope, just sqrt 21, that's the GM

Best ResponseYou've already chosen the best response.0so I just leave it at square root 21?

Best ResponseYou've already chosen the best response.0why do i leave it at \[\sqrt{21}\] ?

Best ResponseYou've already chosen the best response.1Is there something wrong with sqrt 21 ?

Best ResponseYou've already chosen the best response.0don't I have to actually sqaure root it and make it X *\[\sqrt{X}\]

Best ResponseYou've already chosen the best response.0or something like that?

Best ResponseYou've already chosen the best response.1I don't understand, the square root of 21 is roughly 4.5825, unless you are asked to give a decimal approximation, just leave it as sqrt 21
