Study Notes
Exponents and Powers
- The product of $a^m$ and $a^n$ is represented by the expression $a^{m+n}$.
- When $a = 2$ and $m = 3$, the value of $a^m$ is $2^3 = 8$.
- When $a = 5$ and $n = -2$, the value of $a^n$ is $5^{-2} = \frac{1}{5^2} = \frac{1}{25}$.
- The product of $a^m$ and $a^n$ can also be represented as $a^{m} \times a^n$.
- When $a = 2$ and $n = -3$, the value of $a^n$ is $2^{-3} = \frac{1}{2^3} = \frac{1}{8}$.
- When $a = 3$ and $m = 4$, the value of $a^m$ is $3^4 = 81$.
