#### DESCRIPTION:

Learn how to simplify expressions like (5^6)/(5^2). Also learn how 1/(a^b) is the same as a^-b. Towards the end of the video, we practice simplifying more complex expressions like (25 * x * y^6)/(20 * y^5 * x^2).

#### OVERVIEW:

Using exponent rules to evaluate expressions is a free educational video by Khan Academy.It helps students in grades 8 practice the following standards 8.EE.A.1.

This page not only allows students and teachers view Using exponent rules to evaluate expressions but also find engaging Sample Questions, Apps, Pins, Worksheets, Books related to the following topics.

**
1. 8.EE.A.1 :** Know and apply the properties of integer exponents to generate equivalent numerical expressions. For example, 3^2 × 3^(–5) = 3^(–3) = 1/(3^3) = 1/27..
