If P and q are unequal primes,m and n are unequal positive integers satisfyingm2-pm+q=0 andn2-pn+q=0then the value of p+qis.(英汉词典:prime质数) 答案 5解:设m,n是方程x2-px+q=0的两个正整数根,∴由韦达定理得m+n=p,mn=q,又∵p,q都是质数,∴只有当m=1,n=2或m=2,n=1时符...
If pq<1, and p and q are positive integers, which of the following must be greater than 1 ? 选项: A、√pq B、pq2 C、p2q D、qp2 E、qp 答案: E Problem Solving 提问 最新 问个问题 我想问: 提交 最热提问 [Issue Essay]Analytical!... [Issue Essay]Analytical!... [Issue ...
∴p+q=m+n+mn=3+2=5. 故答案为:5. 点评:本题考查了根与系数的关系,属于基础题,关键是掌握x1,x2是方程x2+px+q=0的两根时,x1+x2=-p,x1x2=q,然后再根据已知条件正确进行求解. 练习册系列答案 单元智测卷系列答案 课课练小学英语AB卷系列答案 ...
If n and p are different positive prime numbers, which of the integers n4, p2, and np has (have) exactly 4 positive divisors ?() A.n4only B.p3only C.nponly D.n4andnp E.p3andnp 答案 E [解析] 因为n和p是互不相同的质数,所以根据质因子求解公式可得n4和p3。的因子数分别为4+1=5个和...
