# Question #7f781

This is just pure coincidence that

#2+2=2*2=2^2#

4 is a perfect square number, meaning that if you multiply a number (let's say

#3*3=9#

That means 9 is a perfect square. But 6 is not.

Refer to square roots. They are basically a reversal to an

#sqrt(a^2)=a#

If 9 is square rooted:

#sqrt(9)=3#

and if 4 is square rooted:

#sqrt(4)=2# .

BUT if 6 is under a square root:

#sqrt(6)~~2.44948974278...#

You don't get a pretty, round integer perfect squares have to offer.

It is just a mathematical "miracle" that

I mean, there are triangles ... but I digress.
