Negative Exponent Rule

The video tutorial reviews the negative exponent rule, addressing common misconceptions that negative exponents result in negative values. It presents a math question asking which expression is greater than zero, with four answer choices. The tutorial explains that a base raised to a negative exponent equals the reciprocal with a positive exponent. It eliminates answer choices A and B due to negative values and evaluates choices C and D, confirming C as the correct answer. The video concludes with a summary of interpreting negative exponents.

What is a common misconception about negative exponents?

• They make the base value positive.

• They have no effect on the base value.

• They double the base value.

• They make the base value negative.

What happens to the exponent when you take the reciprocal of a base with a negative exponent?

• The exponent remains negative.

• The exponent doubles.

• The exponent becomes positive.

• The exponent becomes zero.

Why can answer choices A and B be eliminated?

• They result in a positive value.

• They have a positive exponent.

• They have no exponent.

• They result in a negative value.

How is the expression -4 to the -4 rewritten?

• 1 / (-4)^4

• -4^4

• (-4)^4

• 1 / 4^4

Why is the expression 1 / -5 to the +5 negative?

• It has a positive base.
