Exploring Zero Power and Negative Exponents

The video tutorial covers the last two exponent rules: the zero power rule and the negative exponent rule. The zero power rule states that any number raised to the power of zero equals one. Several examples are provided to illustrate this concept, emphasizing that the entire expression must be to the zero power for the rule to apply. The negative exponent rule is then introduced, explaining that a negative exponent indicates the reciprocal of the base raised to the positive exponent. Examples are given to demonstrate how to simplify expressions with negative exponents, including more complex cases involving multiple variables and powers.

What is the result of any number raised to the zero power?

• Undefined

• 1

• The number itself

• 0

If you have an expression inside parentheses raised to the zero power, what is the result?

• The expression's value

• 0

• The base number

• 1

How does the zero power rule apply to a product of variables and numbers?

• The rule does not apply

• The entire product is considered one entity and equals one

• Only the numbers are raised to the zero power

• Only the variables are raised to the zero power

What is the result of a negative exponent?

• The reciprocal of the base raised to the positive exponent

• 0

• Undefined

• The base itself

How do you simplify an expression with a negative exponent in the denominator?

• By setting the expression to zero

• By leaving it as is because it's already simplified

• By converting the base to its reciprocal

• By moving it to the numerator and changing the sign to positive

What happens when you raise a fraction to a negative exponent?

• The fraction is squared

• The fraction's exponent sign changes to positive

• The fraction is inverted and the exponent sign changes to positive

• The fraction becomes undefined

If a variable with a negative exponent is in the numerator, where should it be moved?

• It remains in the numerator with a positive exponent

• It is eliminated from the expression

• To the denominator with a positive exponent

• It remains in the numerator with a negative exponent

What is the simplified form of a variable to the negative second power?

• 1 over the variable squared

• The variable to the fourth power in the denominator

• The variable squared in the numerator

• The variable squared in the denominator

How do you handle a negative exponent outside of parentheses affecting multiple variables inside?

• Apply the exponent to each variable individually

• Invert the entire expression inside the parentheses

• Ignore the exponent since it's outside

• Multiply the exponent by each variable's exponent inside

What is the result of an expression with a base raised to a negative exponent, then squared?

• The base squared in the denominator

• The base to the fourth power in the denominator

• The base squared in the numerator

• 1 over the base squared
