x > 0 so, x = + sqrt(161)

We know that 12^2 = 144 and 13^2 = 169, hence, best approximation is 13

Option A

Hi dave13,

First of all Difficulty is calculated automatically on the basis of results of a number of attempts on a particular question. You can see it in the timer statics (only after a certain number of attempts has been made).

Now, To post a question, one of the difficulty level must be tagged.

Simple solution for you - Just click on "Hide Tags" on any question opened in the browser. So next time when you click on question URL from the butler project page or anywhere, you will not see the tags. When you need to see tags just click on "Show Tags".

Hope it helps :)
