Is 13 a cube number?

There is a finite set of numbers which cannot be expressed as the sum of distinct positive cubes: 2, 3, 4, 5, 6, 7, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26. Mahler proved that 1 has infinitely many representations as three signed cubes.

Why is 13 a prime number?

Prime number is a positive natural number that has only two positive natural number divisors – one and the number itself. Prime numbers are subset of natural numbers. A natural number is a positive natural number that has at least one positive divisor other than one or itself. So 13 is a prime number.

Is 21 a square number?

Informally: When you multiply an integer (a “whole” number, positive, negative or zero) times itself, the resulting product is called a square number, or a perfect square or simply “a square.” So, 0, 1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, and so on, are all square numbers.

Why is 21 not a perfect square?

Example, 11, 21, 51, 79, 76 etc. are the numbers which are not perfect square numbers. We cannot say that the rest of the numbers are perfect square numbers just because they end with 0, 1, 4, 5, 6 or 9. Example 62411 ends with 1 but it is not a perfect square number.13

What does it mean 42?

42 pops up as a clever allusion—and tribute—to Douglas Adams’s book in popular culture. 42, in The Hitchhiker’s Guide to the Galaxy by Douglas Adams, is the “Answer to the Ultimate Question of Life, the Universe, and Everything”, calculated by a supercomputer named Deep Thought over a period of 7.5M years.

How can you tell that 42 is divisible by 3?

When checking if a number is divisible by 3, the easiest way to check this is to sum up the digits in 42 and if that resulting number is divisible by 3, then 42 is too. We can see that the sum of the digits in this case is 6 and this number IS divisible by 3, which means that 42 is also divisible by 3.
