Rational Exponents

So many rules and so little time. Make it easy and provide all the exponent and radical rules in one place as an easy reference guide. All of the properties come with several examples to show how the rules apply to different problems. 

This assessment pair goes way beyond simple graphing, factoring and solving polynomial equations, really forcing learners to investigate the math ideas behind the calculations. Short and to-the-point questions build on one another,...

What is that fraction doing as an exponent? Fun math games prompt learners to practice evaluating radical expressions and expressions containing rational exponents, both in groups and individually.

There are many ways to approach finding the rational approximation of an unknown square root. Here is a problem that will help math learners make a connection between square roots and their order on a number line. As usual, determine two...

Continue your lecture on radical equations with this video, which features Sal solving a few more problems with his classic clarity and understandable way. Young mathematicians will benefit immensely from seeing his cool hand guide the...

In this video, Sal brings it all together and incorporates the concepts from previous lectures (quadratic formula, multiplying polynomial expressions, radical expressions, exponents). This video would be a great way to end a unit or...

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...

This video focuses on a series of problems involving exponent properties. Sal demonstrates rational expressions, simplifying fractions, and manipulating algebraic equations using exponents and division.

Cancel that! Young mathematicians see how factoring and canceling can be very beneficial. The presenter works through examples of multiplying two rational expressions where the factors are simplified first. Factoring complex rational...

Combine the given radical expressions. How? Do they have the same radical? Yes. Then they can be combined. Watch this video as the teacher explains how to combine the terms that can be combined and leave the terms as they are that need...
