Explain what an exponent is, using examples.

For example, if you have $b \times b \times b$, the variable $b$ is multiplied by itself 3 times. This can be written as $b^3$. Here, $b$ is the base, and 3 is the exponent.

Similarly:

• $m \times m \times m = m^3$
• $r \times r \times r = r^3$
• $k \times k \times k = k^3$
• $n \times n \times n = n^3$
