Thanks for the advice guys
I didn't think about the prime number thing haha, I was able to come up with something after that
So I think the answer is realising squares of prime numbers have three divisors, to find how many there are find all prime numbers below 999 square rooted
This should be up to 961 which was 31 squared
If I count this I get 11 prime numbers
I think this is right.
I am solving a daily math problem it's asking:
How many integers between 1 and 999 have 3 divisors?
I'm not sure where to start with this. I don't think there's a systematic way to find how many have 3 divisors
I also don't think there is a way to use algebra for this
Could anyone give advice on where to start. I'm kind of stumped.
