What is a cubed number?A “number cubed” refers to the multiplication of the number with itself and again by itself, i.e., multiplication of the same number two times. In other words, we can find the cube of a number by multiplying the square of a number by the number itself. A c...
A number is multiplied by 3 and then 5 is added. The result is 26. What is the number? A. 7 B. 8 C. 9 D. 10 相关知识点: 试题来源: 解析 7。解析:设这个数为 x。根据题意可得 3x + 5 = 26。移项可得 3x = 21,解得 x = 7。涉及的英语表达有 multiplied by(乘以),added(加上...
解析 A。解析:Since the result is 36 and it was obtained by multiplying by 2 after increasing by 8, we divide 36 by 2 to get 18. Then, since 18 was obtained by increasing the original number by 8, we subtract 8 from 18 to find the original number which is 10....
It's quicker to get the prime factorisation, then calculate the sum of all factors from that, than it is to loop all the way up to sqrt(n) for every number. If you're looking for really big amicable pairs, say bigger than 2^64, then on a small number of machines you can't do ...
Adding zero to a number gives the number itself. Adding 1 to a number gives the successor of that number. Changing the order of the addends does not change the sum. For example,5+3+2=5+2+3=10 Conclusion Adding numbers is a fundamental mathematical process that combines two or more num...
I'm not going to argue with you that "just in case you've worked so hard to write good algorithmic code itself is badly written", hindsight is inherently flawed, and it's not a useful metric for us: First of all, post hoc statistical methods rely too much on the computer's software...
If a number is multiplied by 5 and then 3 is added, the result is 28. What is the number? A. 5 B. 10 C. 4 D. 8 相关知识点: 试题来源: 解析 C。本题考查数学问题的逆向思维。设这个数为 x,根据题意可得 5x+3=28,移项可得 5x=25,解得 x=5。选项 A 是错误计算结果;选项 B 和 ...

Unfortunately, no additional bound beyond the inequalities provided by the Bombieri asymptotic sieve is known, even if one assumes all other major conjectures in number theory than the prime tuples conjecture and its variants (e.g. GRH, GEH, GUE, abc, Chowla, …). To put it another way, ...
