Answer:
Step-by-step explanation:
The expression \( x^{-3} = \frac{1}{x^3} \) illustrates the property of **negative exponents**. Specifically, this property states:
\[ x^{-n} = \frac{1}{x^n} \]
where \( n \) is a positive integer. This property tells us that a negative exponent on a variable or number is equivalent to taking the reciprocal and applying a positive exponent of the same magnitude. Therefore, \( x^{-3} \) is equal to \( \frac{1}{x^3} \) because raising \( x \) to the power of -3 is the same as taking the reciprocal of \( x^3 \).
This property is fundamental in simplifying expressions involving negative exponents and understanding how exponents behave in algebraic equations and identities.
