-32,814Since the last digit is a4, this is aneven numberand therefore divisible by 2. Check if any number is divisible by two. Type in any number that you want, and the calculator will use the rule for divisibility by 2 to explain the result. ...
答案 能被5和7除尽的必定能被35除尽,但不一定能被70除尽,要能被70除尽,需要同时能被5,7,2除尽 相关推荐 1 divisible到底是能被除尽还是整除的意思 题目是这样的说n is divisible by both 5and 7 then n must also be divisible by 但是我觉得要是说是像字典里一样解释为除尽的话 那不是应该也能...
解析 C 12=22×3,15=3×5,而n能够被12和15整除,那么n就至少具有因子22,31,51,选项中哪个数能够由上面因子中的一个或者几个相乘得到,那么这个数就一定能够整除n;25具有两个因子5,不行;16具有4个因子2,也不行;30=2×3×5,2,3,5全部可以为n的因子,因此30一定能够整除n,选择C。
1) 8 is divisible by 2. 8能被2除 2) Exactly divisible by2. 恰能被2整除的 3) 6 divides by 2.; 2 goes into 6. 6能被2除尽。 4) 8 divided by 4 is 2. 8除以4得2。 5) Divide8 by 2, and you get 4. 8除以2得4。

Since the greatest common factor of 12 and 20 is 4, the least common multiple is 12 * 20 ÷ 4 = 60. (Notice that 60 is 12 * 5 and also 20* 3.) Notice that the only integer among the choices that is a factor of 60 is (A) 15....

进而可得商为 N/(11)=(99a+11b+a-b+c)/(11)=9a+b+(a-b+c)/(11)=a^2+b^2+c^2 . 由于a,b,c都是数字,所以容易验证 -8≤a-b+c≤18 . 下面,我们分两种情况讨论: ①a-b+c=0或者②a-b+c=11. 这样原问题可等价于 ① \(a-b+c=0a^2+b^2+c^2=9a+b. , ② \(a-b+c=11a...
is divisible by 12n, we first need to express 12 in terms of its prime factors: 12=22×31 This means that 12n=(22×31)n=22n×3n. Therefore, we need to find the maximum n such that 123! has at least 22n and 3n. Step 1: Calculate the highest power of 2 in 123! To find the...
