Teaching Transcript

🎙️

Let's multiply these exponents.

We can expand both exponents first.

And if we multiply, we have 'C' multiplied by itself 5 times on the bottom.

Which is 1 over 'C' to the power of 5, or 'C' to the power of negative 5.

Multiplying exponents means adding the powers. Minus 2 plus minus 3 is equal to minus 5.
