This my re-re-re-re-repost
The answer form requests square root, they gave integer form (6, 2), which indicates inaccuracy
If people answer you need to respond to them on the original post.
It is rude to just ignore an answer.
Think how you would feel if you tried to help someone and they completely ignored you.
Also, it appears that you are just looking for an answer, not an explanation.
Your complaint is that the answer didn't work, not that you could not understand the logic.
