### Example Question #501 : Isee Upper Level (Grades 9 12) Mathematics Achievement

Evaluate:

**Possible Answers:**

**Correct answer:**

Based on the power rule for exponents we can write:

That means; to raise a power to a power we need to multiply the exponents. In addition, based on the product rule for exponents in order to multiply two exponential terms with the same base, we need to add their exponents:

So we can write:

### Example Question #1 : How To Multiply Exponents

Simplify:

**Possible Answers:**

**Correct answer:**

Based on the product rule for exponents in order to multiply two exponential terms with the same base, add their exponents:

So we can write:

### Example Question #1 : How To Multiply Exponents

Evaluate:

**Possible Answers:**

**Correct answer:**

Based on the power rule for exponents we can write:

That means; to raise a power to a power we need to multiply the exponents. In addition, based on the product rule for exponents, in order to multiply two exponential terms with the same base we need to add their exponents:

So we can write:

in order to divide two exponents with the same base, we can keep the base and subtract the powers. So we get:

### Example Question #1 : How To Multiply Exponents

Evaluate:

**Possible Answers:**

**Correct answer:**

Based on the negative exponent rule we have:

which says negative exponents in the numerator get moved to the denominator and become positive exponents. And negative exponents in the denominator get moved to the numerator and become positive exponents. So we can write:

In addition, based on the power rule for exponents we can write:

That means; to raise a power to a power we need to multiply the exponents. We also know that when a fraction is raised to a power, the numerator and the denominator are both raised to that power. So we can write:

### Example Question #1 : How To Multiply Exponents
