Khan Academy: Exponent Properties: Radical Expressions With Higher Roots

Many times budding algebrists are fine when plugging specific numbers into expressions, but less certain when the range of acceptable values is undetermined. This detailed presentation helps the class move from the point value to...

A series of problems involving exponent properties is the focus of this video. Sal demonstrates rational expressions, simplifying fractions, and how to manipulate algebraic equations using exponents and division.

After a short review on exponents, Sal moves ahead to incorporate exponent properties into his sample problems. This video is a great resource for those who need both the steady pace of Sal's instruction, and also for those who need the...

Video first finding the square root of an integer and then working towards finding larger roots of numbers by utilizing fractional exponents and exponent rules. Highest root is the 6th root. Includes an example with a variable. Video is...

In this video lesson students find the volume of a cube in which the side lengths are exponential expressions.

In this video lesson students learn about radical equivalents to rational exponents.

If your class has a grasp of square roots, but is having difficulty with the product property of square roots, this video might be for you! In the video, an instructor completes a short proof of the property, defines the property, and...

Before defining the quotient property of square roots, the teacher in this video works through an example that shows how the property is possible. She then goes through a couple more examples of the property in action. Show this resource...
