Title: Tricky math question
Post by: Diane CBPFC on August 31, 2009, 11:58:03 PM: One year ago, I was in my prime.
Twelve years ago, I was a power of a prime.
Now, my digits are powers of primes.

Post by: Diane CBPFC on September 02, 2009, 04:44:01 AM: The answer is apparently 44.

As I've always said there are three kinds of people in the world; those that can count and those that can't.

I thought, "I wonder if Mince would know of of a maths expert?".

It's a question? I thought you were just boasting.

Post by: Tom on September 02, 2009, 07:47:02 PM: I'm confused now.

The answer is 44.

One year ago, I was in my prime.
That makes 43. Yep, 43 is a prime number. I can see that.

Twelve years ago, I was a power of a prime.
Is this twelve years from now (44) or one year ago?
If from now, twelve years ago is 32, which isn't a prime number. 31 is a prime number however. And can't any number be a power? 24 to the power of 10 etc? Ah, but 2 to the power of 5 equals 32. I'm getting there...

Now, my digits are powers of primes.
Got it! 2 to the power of 2 is 4!

I'm not confused now.
