Although we have different bases, we know that .

Therefore,

.

Finally, we factor out to get

.

When multiplying exponents, we just add the exponents while keeping the base the same.

When multiplying expressions with the same variable, combine terms by adding the exponents, while leaving the variable unchanged. For this problem, we do that by adding 2+1, to get a new exponent of 3:

When multplying exponents, we need to make sure we have the same base.

Since we do, all we have to do is add the exponents.

The answer is .

When adding exponents, we don't multiply the exponents but we try to factor to see if we simplify the addition problem. In this case, we can simplify it by factoring . We get .

Express as a power of ; that is: .

Then .

Using the properties of exponents, .

Therefore, , so .

Express as a power of ; that is: .

Then .

Using the properties of exponents, .

Therefore, , so .

When adding exponents, you want to factor out to make solving the question easier.

We can factor out to get

.

Now we can add exponents and therefore our answer is

.

When adding exponents, we don't multiply the exponents but we try to factor to see if we simplify the addition problem. In this case, we can simplify it by factoring . We get .

When we multiply two polynomials with exponents, we add their exponents together. Therefore,
