Dividing in Scientific Notation

This video tutorial teaches how to divide numbers in scientific notation by applying the quotient rule for exponents. The lesson begins with a review of the quotient rule, explaining how to divide coefficients and subtract exponents. The tutorial then demonstrates the process through several examples, highlighting the importance of ensuring the final answer is in proper scientific notation. Key steps include dividing the factors, keeping the base of 10, and adjusting the decimal point when necessary.
