By The Organic Chemistry Tutor

This algebra 1 & 2 video tutorial shows you how to simplify radicals with variables, fractions, and exponents that contains both square roots, cube roots, and variables such as x, y, and z. This video contains plenty of examples and practice problems.Here is a list of topics: 1. Simplifying Radical Expressions With Variables & Exponents 2. Simplifying Radicals With Fractions & Variables 3. Radicals With Square Roots & Cube Roots 4. Radical Expressions with X, Y, and Z 5. Absolute Value - Simplifying radical expressions

Sal explains the relationship between radical notation and unit-fraction exponents, including a discussion of what the principal square root is. Then he shows how to simplify the 6th root of (64x^8) using the properties of exponents.

This video provides a basic introduction into free radical reactions. It explains the reactivit-selectivity principle between Chlorine and Bromine and it explains how to calculate the relative percent yields of each monochlorinated product. It discusses heterolytic and homolytic cleavage as it relates to the formation of radicals as well as how to identify initiation, propagation and termination steps in a radical reaction.

Simplify numerical radical expressions with multiple terms

Sal shows how to manipulate expressions like 1/2 and 12/(2-5) so there's no radical in the denominator. This is called rationalizing the denominator.45
