How to find the LCD to help determine the sum between two rational expressions

The video tutorial explains how to determine the least common denominator (LCD) using consistent numbers and the rules of exponents. It covers the process of breaking down numbers and variables, applying exponent rules, and calculating the LCD for both numbers and variables. The tutorial concludes with a demonstration of simplifying expressions by combining terms and ensuring they are like terms.

Describe the process of determining the LCD for variables in an expression.
