## Why is a number to the zero power 1?

In short, the multiplicative identity is the number 1, because for any other number x, 1*x = x. So, the reason that any number to the zero power is one is because any number to the zero power is just the product of no numbers at all, which is the multiplicative identity, 1.

## Why is 1 a triangular number?

Triangular numbers correspond to the first-degree case of Faulhaber’s formula. Alternating triangular numbers (1, 6, 15, 28.) are also hexagonal numbers. where Mp is a Mersenne prime. No odd perfect numbers are known; hence, all known perfect numbers are triangular.

## How do you identify triangular numbers?

Triangular Number Sequence

1. The first triangle has just one dot.
2. The second triangle has another row with 2 extra dots, making 1 + 2 = 3.
3. The third triangle has another row with 3 extra dots, making 1 + 2 + 3 = 6.
4. The fourth has 1 + 2 + 3 + 4 = 10.
5. etc!

## What is 0 raised to a power?
