Numbers That Are Powers of 3
A number that is a power of 3 means you get it by multiplying the number 3 by itself a certain number of times. For example:
- 3 to the power of 1 is 3 (3)
- 3 to the power of 2 is 9 (3 × 3)
- 3 to the power of 3 is 27 (3 × 3 × 3)
- 3 to the power of 4 is 81 (3 × 3 × 3 × 3)
We write this as 3n, where n is how many times you multiply 3 by itself. These numbers are very important in areas like computer science and puzzles.
The Third Power of a Number
The third power of a number is when you multiply any number by itself three times. For example:
- The third power of 2 is 8 (2 × 2 × 2)
- The third power of 4 is 64 (4 × 4 × 4)
We write this as n3, where n is the number you are multiplying. This is also called "cubing" a number, because if you imagine a cube, its volume is found by multiplying its side length by itself three times.
