INDEX LAWS 2 | Dealing with negative indices and reciprocals.

Understand how to deal with Negative Index Numbers. Learn how to find the reciprocal of a number.
Key Concepts:
* Index Basics: Revisit the concept of indices representing repeated multiplication of a base number.
* Introducing Negative Indices: Explore the concept of negative indices, a notation used to represent the reciprocal of a power. See how a negative index (a^-n) is equivalent to 1 divided by the base number raised to a positive power (a^n).
* Reciprocal Power: Learn how to find the reciprocal of a number, which is essentially the value that, when multiplied by the original number, equals 1. Understanding reciprocals is crucial for working with negative indices.
By the End of This Video, You'll Be Able To:
* Use the rule: a^-n = 1 / a^n to convert negative indices into expressions with positive exponents.
* Calculate the reciprocal of a number effectively.
* Apply your understanding of negative indices and reciprocals to simplify expressions and solve problems involving exponents (Power/Index Number).
