Positive Integers: Positive integers are natural counting numbers greater than zero. They are sometimes denoted by $Z+$. Examples of positive integers are 1, 2, 3, 4, 5, 6, 7, . . .Negative Integers: Negative integers are integers with a value less than zero. They are represented by $...
1Assume that a,b,c,d are integers,and four equations (a-2b)x=1,(b-3c)y=1,(c-4d)z=1,w+100=d have always solutions x,y,z,w of positive numbers respectively,then the minimum of a is .(英汉词典:to assume假设;integer整数;equation方程;solutions (方程的)解;positive正的;respectively...
If n=p+r, where n, p, and r are positive integers and n is odd, does p equal 2 ?() (1)p and r are prime numbers. (2)r≠2 A.条件(1)充分,但条件(2)不充分. B.条件(2)充分,但条件(1)不充分. C.条件(1)和(2)单独都不充分,但条件(1)和条件(2)联合起来充分....
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...
