1. Let's start by understanding what power means in mathematics. 2. Power refers to exponentiation, which means multiplying a number by itself a certain number of times. 3. For example, $a^n$ means multiply $a$ by itself $n$ times. 4. Here, $a$ is the base and $n$ is the exponent or power. 5. If $a=2$ and $n=3$, then $2^3 = 2 \times 2 \times 2 = 8$. 6. This operation is repeated multiplication and is one of the fundamental arithmetic operations. Final answer: Power represents the operation of exponentiation where a base number is raised to an exponent, such as $a^n$ meaning the base $a$ multiplied by itself $n$ times.
