Hi All,
Not sure how to make a new post. So I will put my question right here.

Q: The minimum value of the expression is attained at x=a. If 'x' is always greated than 5, then what is the value of 'a'?

1. 6
2. 5+2^(1/2)
3. 5+1/(3^(1/2))
4. 5+1/(5^(1/2))
5. None of these.

Request you to put the explanation as well.
Thanks is advance for any replies.

This was fun though. We should look on the positivity we could extract from this post, rather than harsh commenting.
