I suppose you could have 13, 23,33,43 and 53 or plenty others as alternatives.
Perfect cubes.
Yes. In fact, they are integers.
1331 and 2197
Answer: 1, 64, & 729
The perfect cubes between 100 and 200 are 125 (5^3) and 216 (6^3).
The cube root of 5000 is approx 17.1 So the numbers 1 to 17 have cubes which are smaller than 5000 that is, there are 17 such numbers.
There are no perfect numbers between 20 and 30. Perfect numbers are numbers that are equal to the sum of their proper divisors, excluding the number itself. The perfect numbers within this range would be 28, but that is incorrect as 28 is not a perfect number.
The sum of the first five prime numbers is 28. The sum of the cubes of the first three prime numbers is 160. The average of 28 and 160 is 94.
64 is the square of 8 and the cube of 4.
1, 8, 27, 64, and 125
I believe there are 2 positive three-digit perfect cube numbers, that are even.
Between the two numbers there are only two.
