求解一道GMAT OG if r and s are positive integers,can the fraction r/s be expressed as a decimal with only a finite number of nonzero digits?(1) s is a factor of 100(2) r is a factor of 100
(1) s is a factor of 100(2) r is a factor of 100 下载作业帮APP学习辅导没烦恼 答案解析 结果1 举报 既然是100的因数就不用一般证明了咯,因为100的因数就只有1,2,4,5,10,20,25,50,100这几个,两个一除剩下的顶多是1/100也就是0.01,其它都是0.01的倍数.等等.我们看到的是同一道题目吗?为什么...

翻译:如果n和m是正整数,m是62的因子,那么 62=2x31 m is a factor of 62,=> m=1 or 2, or 31 or 62 n and m are positive integers 3n= 36/m m=1 =>n=12 m=2, =>n=6 m=31, =>n= 12/11 ( rej )m=62, =>n=6/31 (rej)the greatest possible number of integers...
3 is a prime number 4 is a factor,25!=4*1*2*3*5*6*...*25 25!指的是25阶乘=25*24*...*1 5显然是factor 6,7,8,9,10,...,25显然都是factor 26=2*13也是 27=3*3*3,25!中有3和9,所以也是factor 28=4*7,factor 29是prime 30=3*10 31prime 32=4*8,factor 33=3...
题目的意思是 问 1+i 是否是多项式 p(X)=x3次方-2x平方+2x的一个因式?而P(x)=x*(x-1+i)*(x-1-i) 很明显 1+i 是P(x)=0的一个根,不是P(x)的一个因式。。。
