Ques１: If the prime numbers p and t are the only prime factors of the integer m, is m a multiple of p^2t?
(1) m has more than 9 positive factors.
(2) m is a multiple of p^3.
Ques 2: The function f is defined for all positive integers n by the following rule: f(n) is the number of positive integers each of which is less than n and has no positive factor in common with n other than 1. If p is any prime number, then f(p)=
A) p – 1 B) p – 2 C) p+1 / 2 D) p-1 / 2 E) 2
第一题，不明白，为什么(1)不行。
第二题，实在是没看明白NN的解释。 |
