Simplifying Expressions with Negative Exponents

The video tutorial covers the application of exponent rules in algebraic expressions. It begins by explaining how to distribute exponents across terms within parentheses and highlights the difference between raising a base and an entire term to a power. The tutorial then introduces the 'rule of wrong position,' which involves moving terms with negative exponents to the denominator to make them positive. Finally, it demonstrates simplifying fractions with exponents by canceling terms and flipping fractions to simplify calculations. The video aims to clarify these concepts through step-by-step examples.

What does the parentheses indicate in the expression 2X -4 * 3x -2?

• Neither the 2 nor the X is raised to the 4th power.

• Only the X is raised to the 4th power.

• Both the 2 and the X are raised to the 4th power.

• Only the 2 is raised to the 4th power.

What is the first step in distributing the exponent to the terms inside the parentheses?

• Add the exponents.

• Combine like terms.

• Multiply the exponents.

• Distribute the exponent to each term.
