## Rootin’ Around

The digits of today’s date can be concatenated to make the four-digit number 4913, and 4913 = 173. As it turns out, this is the only date in 2013 for which the concatenation of the digits forms a number that has a square, cube, fourth, fifth, or sixth root that is a whole number.

I’m sure there are more useless pieces of trivia, but I can’t think of one right now.

[Update, 4/9/13: Perhaps the following isn’t more useless, but it’s certainly not more useful, either. I failed to mention the trivial numerology contained within today’s date: 4 + 9 = 13.]

In any case, this fact about the cube root of 4913 got me to thinking about some of my favorite things.

I must be an idiot. I don’t get that last one.

Not an idiot, Joseph. It’s a tough one. I don’t want to just post the answer, as figuring it out is half the fun; so, here’s a hint: http://idioms.thefreedictionary.com/root.

Gah. Finally got it.

Now be honest, Joseph. Just like a good math problem, doesn’t it feel better to figure it out for yourself?

*sigh*

You win.

So this is what my math students feel like when I force them to work through a problem on their own, rather than me just telling them the answer. 😀
