Scientific Notation and Exponents

This video tutorial covers essential exponent and radical rules needed for ninth grade exams. It begins with an introduction to square roots and factor trees, explaining how to simplify both perfect and non-perfect squares. The tutorial then delves into exponents, covering zero and negative exponents, and concludes with a section on scientific notation, demonstrating how to handle large and small numbers. The video aims to equip students with the skills to tackle these mathematical concepts without a calculator.
