01 / QUICK RECAP
Connect the ideas.
- Match the operation to the correct index law; addition is not multiplication.
- A zero power is 1 only for a non-zero base, and a negative power gives a reciprocal.
- Apply an outer power to every factor, including the coefficient.
- Standard scientific notation has a coefficient from 1 inclusive to 10 exclusive.
- Align powers before adding or subtracting scientific quantities.
- Convert to compatible units and interpret the final magnitude.
