第一题 The intergers m and p are such that 2<m<p and m is not a factor of p. If r is the remainder when p is devided by m, is r>1? (1) The greatest common factor of m and p is 2 (2) The least common multiple of m and p is 30 答案选A 我选E。。。。真是不会做。。。。 第二题 If k is a positive integer, is k the square of an integer? (1) K is divisible by 4 (2) k is divisible by exactly for different prime numbers. 这题我不明白第二个条件的意思,K只能被这4个质数整除,是指比如说K只能=2乘以3乘以5乘以7 还是说K可以等于2乘以2乘以3乘以3乘以5乘以5乘以7乘以7这种的 答案给的是B。。。。
