Solution

Dear visitors and friends of the site.

Thank you for your solutions. The first to send the correct one was Jason.

We congratulate him with this! Well done.

 

Here is the correct solution:

Using multiplication by the conjugate radical, the numbers can be rewritten as 3/(sqrt(109)+sqrt(106) and 3/(sqrt(104)+sqrt(101).

The second denominator is smaller, so the second number is greater.

Thank you and try the October 2017 Problem!
