Why is option C the correct answer for the equation?

• Because it is the largest number

• Because it satisfies the equation when substituted

• Because it is the smallest number

• Because it is the only negative option

What is an exponential equation?

• An equation with variables in the base

• An equation with only addition and subtraction

• An equation with variables in the exponent

• An equation with no variables

What mathematical tool is often used to solve exponential equations?

• Division

• Multiplication

• Logarithms

• Fractions

What does the negative exponent property state?

• a^n = a^(-n)

• a^n = 1/a^n

• a^n = a^n + 1

• a^n = a^n - 1

How can you simplify 1/x^(-2) using the negative exponent property?

• x^(-2)

• x^2

What happens to the exponent when you move a power across the fraction bar?

• It changes sign

• It remains the same

• It becomes zero

• It doubles

What is the result of applying the negative exponent property to 12^(-2x)?

• 12^(-2x)

• 1/12^(-2x)
