Divide:  

Possible Answers:

Correct answer:

Explanation:

In order to subtract the exponents, we will need similar bases.  

Rewrite the nine as a base of three.  Nine is equivalent to .

The expression becomes:  

Now that the bases are equal, we can subtract the exponents and simplify.

The answer is:  

Example Question #132 : Multiplying And Dividing Exponents

Simplify:  

Possible Answers:

Correct answer:

Explanation:

In order to simplify this, we will need to convert the base eight to base two.

Rewrite the second term.

Because the bases are now similar, we can add the exponents.

The answer is:  

Example Question #133 : Multiplying And Dividing Exponents

Divide the exponents:  

Possible Answers:

Correct answer:

Explanation:

Rewrite the numerator and denominator using the base power of two.

Use the product rule of exponents to simplify the powers.

Now that the bases are similar, the exponents on the numerator and denominator can be subtracted.

The answer is:  

Example Question #134 : Multiplying And Dividing Exponents

Multiply the terms:  

Possible Answers:

Correct answer:

Explanation:

Use the power rule of exponents to simplify.  Multiply the power of 42 with the power of two outside the parentheses.

When the powers of the same bases are multiplied, the powers can be added.

The answer is:
