This PowerPoint presentation introduces all necessary power rules for eighth grade math students; Multiplying and dividing powers & negative and zero exponents. This PowerPoint covers 8.EE.A.1 and it’s also available with a worksheet.

Contents:

• Recall: Recalling the concepts of exponents and base and also the fact that power is a multiplication.
• Multiplying two powers: Students will learn that whenever you multiply two powers of the same bases, you can combine them by adding the exponents.
• Dividing two powers: We will realize that if you divide two powers with the same base, they can be combined by subtracting the exponents.
• Negative exponents: This slide explains how we can end up with a negative exponent in the first place.
• Rules for negative exponents: Students will learn that a negative exponent can be written as a fraction.
• Zero as exponent: We will learn the rule that whenever the exponent is zero and the base is nonzero the result is 1. We also point out that zero power zero has no result at all.
• All the rules so far: In this slide all the power rules are collected to one slide.
• Why the rules are useful: Students will see some examples of expressions which are almost impossible to calculate without these rules for powers.
• Other examples: Three examples of using the power rules.
