If you approximate Root 5 and Root 7 you will get numbers between 2 - 3 and if you subtract one from another then you will definitely get less than 1 and any fraction if you Square then it will tend towards Zero hence its Zero
This is how I solved it more or less. Just wanted to point out that "if you square any fraction it will tend towards zero hence it's zero" is a bit misleading IMHO. While it is true that x^2 is less than x for all x whose absolute value between 0 and 1, and in that sense "tends" towards 0, this question specifically asked whether x^2 is
closer to 0 or 1. There are plenty of examples, x = 0.75, x = 0.9, etc. where x^2 would be closer to 1 than to 0.
