What do you do when you have multiple exponents in an equation? Do you turn and run or tackle it with ease? With the help of a few exponent rules, you are sure to do the second!

It's true, exponents are powerful, but that doesn't mean you need to be afraid.

Just like most things in math, there are specific properties and rules that you can follow to help you solve such equations.

Let's start with a quick review of exponents.

The *exponent* of a number says* how many times to multiply a number times itself*.

Remember, you take the base times ITSELF, not the base times the exponent! This is a very easy (and common) mistake to make, so be careful.

If you need more time to review exponents, take a look at the Elephango lesson found in **Additional Resources** in the right-hand sidebar.

Now, what about when you stumble across a problem that has *multiple* exponents that are being multiplied, or maybe terms with exponents that are being *divided*? Do you turn around and just run?

No way! There are very specific rules you can follow when you see multiple exponents together in a problem. The following chart shows them. Please take a minute to make a foldable. Grab a piece of paper and fold it into 3 columns. You will need 9 row, so add 8 folds for these rows. Open it up and copy this chart onto it; it will be helpful to use when solving problems today and in the future:

Here are a few more examples of these rules for you to look over:

Notice on the last example how you look at each term separately. You divide the numbers normally, then follow the rules and subtract the exponents for each of the variables.

Please watch this *Exponents Rules Part 1 | Exponents, radicals, and scientific notation | Pre-Algebra | Khan Academy *video to see examples using these exponents rules:

If you feel like your head is spinning with all these rules, remember: you only use one at a time. You can use the chart above to help you out as you work through some problems in this lesson and at any time.

Go to the *Got It?* section now for some practice using these rules.

We help prepare learners for a future that cannot yet be defined. They must be ready for change, willing to learn and able to think critically. Elephango is designed to create lifelong learners who are ready for that rapidly changing future.
