The exponential function \( f(x) = a^x \) passes through the point \( (3, 125) \). To find the value of \( a \), we can substitute the point \( (3, 125) \) into the function.

1. The function is \( f(x) = a^x \).
2. Substituting \( x = 3 \) and \( f(3) = 125 \), we get:
   \[
   125 = a^3
   \]
3. Solving for \( a \), we take the cube root of both sides:
   \[
   a = \sqrt[3]{125}
   \]
   \[
   a = 5
   \]

Thus, the value of \( a \) is \( 5 \), and the exponential function is:
\[
f(x) = 5^x
\]
