Use non-zero base a. In this notation ^ means 'to the power of'. Multiplying same-base powers combines repeated factors; dividing cancels factors. Compare a^2 x a^5, a^7 / a^2, and the DIFFERENT operation a^2 + a^5. Addition does not use the multiplication index law.

- Simplify a^7 / a^2. Why require a to be non-zero?
- Test the false claim a^2 + a^5 = a^7 using a = 2.
