(0:01)Parts of a Power: A power has a base (the number being multiplied) and an index or exponent (the number of times the base is used). For instance, in $5^3$, 5 is the base, and 3 is the index.

(1:00)Special Rules for Indices: Any number to the power of 1 is itself; any non-zero number to the power of 0 is 1; however, $0^0$ is undefined.

(1:30)Square and Cube Numbers: Powers of 2 are called square numbers (e.g., 4, 9, 16), and powers of 3 are called cube numbers (e.g., 8, 27, 64).

(2:30)Using BIDMAS with Powers: In calculations, handle indices before multiplication or division.
