To generate the equivalent expression \( 314 \) from \( 353 - 9 \), the transformation involves using the Property of Negative Exponents. Specifically, \( 353 - 9 \) can be interpreted as \( 353 / 39 \), which simplifies to \( 3^{14} \).
This means we used the Property of Negative Exponents to recognize that subtracting the exponent, as in \( a^m - a^n \), corresponds to dividing the bases when the bases are the same.
Thus, the appropriate response is:
the Property of Negative Exponents and the Product Rule of Exponents.
