Introduction to Logarithm Properties (Part 2), Logarithms
Sal gets to the heart of this video, clarifying that it's important to understand math "so you can apply it later on and not have to relearn everything every time." True to his word, Sal demonstrates ways to solve logs and exponents more...
Khan Academy
Product Rule, Taking Derivatives, Differential Calculus
Sal defines the product rule and then shows two examples of its use. He then shows an example of finding the derivative using the chain and product rules together.
Khan Academy
Exponent Properties Involving Products, Numbers and Operations, 8th grade
After a short review of exponents, Sal incorporates exponent properties into his sample problems. This video is a great resource for those who need Sal's steady pace of instruction and the challenge of more complicated problems.
