### Example Question #1 : Simplifying Exponents

Simplify the expression:

**Possible Answers:**

Cannot be simplified

**Correct answer:**

Begin by distributing the exponent through the parentheses. The power rule dictates that an exponent raised to another exponent means that the two exponents are multiplied:

Any negative exponents can be converted to positive exponents in the denominator of a fraction:

The like terms can be simplified by subtracting the power of the denominator from the power of the numerator:

### Example Question #1 : Generate Equivalent Numerical Expressions: Ccss.Math.Content.8.Ee.A.1

Simplify:

**Possible Answers:**

**Correct answer:**

Use the power rule to distribute the exponent:

### Example Question #1 : Integer Exponents

Simplify the following expression:

**Possible Answers:**

**Correct answer:**

Simplify the following expression:

To raise exponents to another power, we need to multiply them:

So we get:

### Example Question #1 : Generate Equivalent Numerical Expressions: Ccss.Math.Content.8.Ee.A.1

Simplify.

**Possible Answers:**

**Correct answer:**

When an exponent is being raised by another exponent, we just multiply the powers of the exponents and keep the base the same.

### Example Question #3 : Integer Exponents

Simplify.

**Possible Answers:**

**Correct answer:**

When an exponent is being raised by another exponent, we just multiply the powers of the exponents and keep the base the same.

### Example Question #4 : Integer Exponents

Combine the following terms:

**Possible Answers:**

**Correct answer:**

Combine the following terms:

We need to multiply three terms together. We should recognize that the t must be left alone, because it cannot be combined with the x's.

First, multiply all three coefficients

Next, combine the x's. Because we are multiplying, we will add the exponents.

Now, put it all together to get:

### Example Question #5 : Integer Exponents

Evaluate

**Possible Answers:**

**Correct answer:**

When common variables with exponents are divided, the exponents are subtracted.

### Example Question #6 : Integer Exponents

Evaluate

**Possible Answers:**

**Correct answer:**

When like terms with exponents are multiplied, you add the exponents.

### Example Question #7 : Integer Exponents

Evaluate the following:

**Possible Answers:**

**Correct answer:**

When similar terms raised to *n* are multiplied, simply add the exponents. Thus

### Example Question #8 : Integer Exponents

**Possible Answers:**

**Correct answer:**

When similar terms raised to *n* are multiplied, simply add the exponents. Thus
