Scientific Notation and Basic Operations

The video tutorial explains how to simplify an expression and convert it into scientific notation. It begins by identifying parts of the expression already in scientific notation and converting others. The tutorial then demonstrates how to multiply and divide these expressions, ensuring the final result is in proper scientific notation. The process involves rearranging terms, performing arithmetic operations, and adjusting exponents to achieve the desired format.
