nah this is a different book. haven't found any errors yet. that answer is 2r and I showd you how to do it.



For any positive integer n, π(n)

represents the number of factors of

n, inclusive of 1 and itself. a and b

are prime numbers. so which is larger, π(a) + π(b) or π (a +b)



after plugging in any two prime numbers, it seems that the product is only divisible by 1, itself, a, and b. i'm guessing the answer is that both values are equal.



boom, i was right. learn something new everyday about prime numbers. mental masturbation as the intelligent folks would say
