Have you ever tried to multiply a power by a power when there is a monomial? Take a look at this dilemma.
This is a monomial expression that is being raised to the third power. Do you know how to simplify this expression?
Pay attention and you will know how to complete this dilemma by the end of the Concept.
We have raised monomials to a power, products to a power, and quotients to a power. You can see that exponents are a useful tool in simplifying expressions. If you follow the rules of exponents, the patterns become clear. We have already seen powers taken to a power. For example, look at the quotient:
If you focus on just the numerator, you can see that
Here is one.
Take a look at this one.
Apply the Power of a Power Property to each example.
Now let's go back to the dilemma from the beginning of the Concept.
Next, we have to take each part of the monomial and raise it to the third power.
Now we can put it altogether.
This is our solution.
- a single term of variables, coefficients and powers.
- the number part of a monomial or term.
- the letter part of a term
- the little number, the power, that tells you how many times to multiply the base by itself.
- the number that is impacted by the exponent.
- Expanded Form
- write out all of the multiplication without an exponent.
- Power of a Power Property
- the exponent is applied to all the terms inside the parentheses by multiplying the powers together.
Here is one for you to try on your own.
First, we are going to separate each part of the monomial and raise it to the fourth power.
Our final answer is
Directions: Simplify each monomial expression by applying the Power of a Power Property.
