Exponents

Most the videos listed below cover the meaning, basics, and rules of exponents. Bottom of page has link to videos on scientific notation and rational exponents--which require a knowledge of radicals.

Here is a funny quote I found (not sure of author): "You can't teach exponents to atheists- - they don't believe in higher powers."

Exponents - Basics Covers the basic meaning of exponents that are whole numbers and how to evaluate and simplify expressions. Also defines zero exponent.

Exponents 1-definition, meaning and evaluating Shows how to evaluate problems b^n with positive exponents, but where base may be negative. Explains difference when negative sign is in or out of the parentheses.

Exponents 2-Exponents and Evaluating Expressions Shows how to evaluate variable expressions containing exponents,focusing on when you replace a variable base with negative numbers.

NOTE: See attached handout (bottom of page) titled Laws of Exponents. It covers the laws of exponents which are also covered in the videos below. The handout covers more examples, and has a problem set. The answer key to the problem set is also attached.
