What are 2 almost perfect numbers between 5 and 20 without using mathematical signs?
Two almost perfect numbers between five and twenty are six and twelve. Six has divisors one, two, and three, which add up to five, just one less than itself. Twelve has divisors one, two, three, four, and six, summing to sixteen, which is four less than twelve. Both numbers are close to being perfect, as they fall short by a small amount.
Is there any perfect numbers that are in between 1 and 30?
No, there are no known perfect numbers between 1 and 30. The only perfect numbers that have been discovered are 6, 28, 496, and 8128.
How do you find the perfect cube between two numbers?
It is not clear whether or not "between" is to be consider to include either or both of those two numbers. In any case, the solution is not too different in each case. Let's assume that the perfect cube being sought is strictly smaller than the larger of the two numbers given. We take the cube root of that number and round it downward to the nearest integer and then cube it. If that number is greater than (or equal in case "between" is inclusive) to the smaller of the two numbers, then that is the perfect cube being sought. If it is smaller than the smaller of the two numbers, there is no such perfect cube.

What are the two numbers between 5 and 20 that are almost perfect.?
The two numbers between 5 and 20 that are almost perfect are 6 and 28. An almost perfect number is a number that equals the sum of its proper divisors, excluding itself. The proper divisors of 6 are 1, 2, and 3, which sum up to 6. Similarly, the proper divisors of 28 are 1, 2, 4, 7, and 14, which sum up to 28.
