If x is a prime number,y is an integer,and x21-x=2y2+3,then xy2=( )(英汉小辞典:prime number 质数,integer:整数) A. 8 B. 16 C. 32 D. 64 相关知识点: 试题来源: 解析 C 【分析】先根据x是质数判断出21-x是质数,故x21-x一定是质数;再根据y是整数可知y2一定是合数,故y2+3一定...
g is an integer and x is a prime number Find out:Which of these are an integer: (\(g^2\)x+5gx) / x \(g^2\) - \(x^2\)/3 6 (g/2) - 100 \((g/2)^2\)We will take each statement separately and check if they are an integer....
To solve the problem, we need to determine the number of elements in the sets P and M, and then find the difference n(P)−n(M). 1. Define the Set P: - The set P is defined as P={x:x is a prime number and x<20}. - Prime numbers are numbers greater than 1 that have ...

A 若P是比11大的质数(prime number),且p等于两个质数x,y的和.则x可能是下而的哪一个 考生在解答此题时.应比较熟悉质数、奇数与偶数之间的相互关系。P是比11大的质数,所以P必是奇数。而P同时又是两质数的和,由于一个奇数只可能是一个奇数与一个偶数之和,故x、y中必有一个是2(因为除2以外.其他质数...
