    Hint √12 = √ (4 * 3 ) = ....?

    the sqrt(12) = 2 sqrt(3) so sqrt(3) + 2 sqrt(3) is your solution

    sqrt(3) is IMPLIED 1*sqrt(3) . What is 1 + 2?

    All i care about is her understanding the methods on how to get it, regardless of how to do it

    You didn't provide any method, you provided a solution ..... :/ Here, you can rewrite sqrt(12) like @Chlorophyll said.

    sqrt(12) = the terms sqrt(4) * sqrt(3) sqrt(4) = 2 which stays on the outside of the radical 2sqrt(3) + sqrt(3) which is the solution

    either works 3sqrt(3) or sqrt(3) = 2sqrt(3)

    Right, but one is simplified all of the way, and one is not. If you are providing answers to a computer (all too common), it will complain that it is not completely simplified. It's important to see how they add like that.

    I've tutored for years, and I can assure that this is not the case whatsoever. You can continue being indignant though.

    square root 3 value 1.732 so 1.732+2(1.732)=5.196

    That answer will be an approximation (with round off error). The exact answer is that as has been shown.

    They are approximations. You can't always just plug and chug to get numbers out. For example. Pi = 3.14...this is an approximation and is far from exact. Pi, is exact. Similarly sqrt(3)... 1.73 is an approximation. sqrt(3) is exact. When you have problems that grow to a page or fill a chalk board, doing rounding like this will give you VERY wrong answers especially if you do it early in the problem. It's called error propagation. Google it.
