Simplifying Expressions with Exponents

The video tutorial explains how to simplify an expression with exponents, focusing on grouping common bases and converting negative exponents to positive. The process involves rewriting the expression, adding exponents for common bases, and ensuring all exponents are positive by moving terms to the denominator. The final simplified form is presented with positive exponents.

What is the initial expression that needs to be simplified?

• n^2 * r^5 * n^-7

• n^2 * r^5 * n^7
