The video tutorial explains how to expand logarithmic expressions by identifying products within expressions and applying logarithmic properties. It emphasizes that expansion is possible when a product can be rewritten as the addition of logarithms. The tutorial demonstrates this process using an example, showing how to rewrite products and apply exponent rules to achieve the final expanded expression.
