## Algebra: A Combined Approach (4th Edition)

$x^{37}$, A. Add the exponents
Based on the product rule for exponents, we know that $a^{m}\times a^{n}=a^{m+n}$ (where $m$ and $n$ are positive integers and $a$ is a real number). Therefore, we can simplify the given expression by adding the exponents. $x^{14}\times x^{23}=x^{14+23}=x^{37}$
