Understanding Quotient and Negative Exponent Rules

The video tutorial explains how to simplify quotients using the quotient rule and the negative exponent rule. It provides four examples, each demonstrating the application of these rules to simplify expressions with exponents. The tutorial emphasizes expressing answers with positive exponents and explains the reasoning behind the rules. By expanding and simplifying expressions, the video illustrates how to handle common bases and negative exponents effectively.

What does the quotient rule of exponents state?

• When dividing with different bases, multiply the exponents.

• When dividing with different bases, subtract the exponents.

• When dividing with the same base, subtract the exponents.

• When dividing with the same base, add the exponents.

According to the negative exponent rule, what is x^-n equal to?

• x^n

• x^-n

• -x^n

• 1/x^n

In the first example, what is the simplified form of y^2 / y^5 using positive exponents?

• y^2

• 1/y^3

• y^-3

• y^3

What is the result of applying the quotient rule to (3x)^4 / (3x)^6?

• 1/(3x)^2

• (3x)^-2

• (3x)^2

What is the product rule of exponents?

• When multiplying with different bases, add the exponents.

• When multiplying with different bases, subtract the exponents.

• When multiplying with the same base, add the exponents.

• When multiplying with the same base, subtract the exponents.

In the third example, what is the simplified form of y^3 * y^2 / y^9?

• y^4

• 1/y^4
