Power Rule for Exponents

Youngsters respond to 10 problems that require them to calculate the products of the powers of 10 and write numbers in exponent form.

Teach the basics of exponent expressions. A video defines an exponent and demonstrates its meaning using several examples. Examples include variables and both positive and negative integers

The problems in this video contain additional examples of scientific notation, continued from the previous presentation. Viewers have the opportunity to see Sal work through several more problems using the same techniques he has been...

Introduce the Quotient Rule for exponents with a video that models how to divide powers. The instructor works through five examples with variable bases to cover the concept.

This presentation covers the basic definition of exponents, raising something to the exponent zero, simplifying negative exponents, multipling powers of the same base, and dividing powers with the same base. The presenter then considers...

The laws of exponents are explained in this video. Topics include raising something to the zero power, rewriting an expression that has a negative number as an exponent, multiplying powers with the same base, raising a power to a power,...

Both positive and negative numbers play a part in this video. Here, Sal explains the definition and function of exponents. Especially helpful for those with the tendency to multiply an integer by its exponent, this video offers several...

Identify the base, identify the exponent, write out the base the number of times indicated by the exponent. Then multiply the base as written out in expanded form. Finally simplify your answer and you will have just evaluated an exponent.

An instructor walks viewers through a complicated problem in which she divides 2 rational expressions. For this problem, she has to find excluded values, use the zero product property, multiply, divide, cancel, and simplify. This video...

A monomial raised to a power needs to be multiplied. No problem. Use the product of a power rule and the power of a power rule too. Now all that needs to be done is to simplify the product.
