To model the number of words \( y \) that the AI can learn after \( x \) hours, we can use an exponential growth equation. The initial number of words the AI knows is 125, and it doubles its vocabulary every 8 hours.
The general form of the exponential growth equation is:
\[
y = a \cdot b^{(x/t)}
\]
where:
- \( a \) is the initial amount (125 words),
- \( b \) is the growth factor (2, since it doubles),
- \( x \) is the time in hours,
- \( t \) is the time period over which the doubling occurs (8 hours in this case).
Plugging in the values, we get:
\[
y = 125 \cdot 2^{(x/8)}
\]
This equation models the number of words \( y \) the AI can learn after \( x \) hours.

While the primary model for the growth of the AI's vocabulary is \( y = 125 \cdot 2^{(x/8)} \), alternative forms can be used to represent the same underlying exponential growth concept. Here are a few variations of the equation:
1. **Using Base \( e \)**: You can express the equation using the natural exponential function:
\[
y = 125 \cdot e^{(k \cdot x)}
\]
where \( k \) is the growth constant. In this case, since the vocabulary doubles every 8 hours, you can find \( k \) such that:
\[
e^{(k \cdot 8)} = 2 \quad \Rightarrow \quad k = \frac{\ln(2)}{8}
\]
Thus, the equation can be written as:
\[
y = 125 \cdot e^{\left(\frac{\ln(2)}{8} \cdot x\right)}
\]
2. **Discrete Time Steps**: If you want to express the vocabulary growth in terms of discrete time steps (every 8 hours):
\[
y = 125 \cdot 2^{(n)}
\]
where \( n = \frac{x}{8} \). So you would have:
\[
y = 125 \cdot 2^{(x/8)}
\]
3. **Unit Conversion**: If you express time in terms of the number of 8-hour periods \( t \) (where \( t = \frac{x}{8} \)):
\[
y = 125 \cdot 2^{t}
\]
where \( t \) is the number of 8-hour intervals that have passed.
4. **General Exponential Format**: You can also represent the growth in a more general format:
\[
y = 125 \cdot (2^{\frac{1}{8}})^{x}
\]
This highlights the idea that the vocabulary growth can be viewed as a continual compounding process, where \( 2^{\frac{1}{8}} \) represents the growth rate per hour.
5. **Polynomial Form Transformation**: If you want to adjust the base to a simpler representation, you could modify the initial conditions slightly or shift the format:
\[
y = 125 \cdot 1.1487^{x}
\]
Here, \( 1.1487 \) is approximately equal to \( 2^{1/8} \), aligning with the idea of continuous growth every hour.
All of these representations capture the exponential growth nature of the vocabulary increase over time, maintaining the same underlying concept of doubling the vocabulary every 8 hours.

Let's evaluate the potential equations you've provided in the context of the original problem where the AI starts with 125 words and doubles its vocabulary every 8 hours.
### Analysis of each equation:
1. **\( y = 8 \cdot (2.5)^{x} \)**:
- This implies that for every hour \( x \), the vocabulary grows based on a factor of 2.5 raised to the \( x^{th} \) power, starting with 8 words. This does **not** align with the problem since it doesn't correctly model the initial vocabulary (125) and the doubling every 8 hours.
2. **\( y = 2 \cdot (2.5)^{x} \)**:
- Similar to the first equation, starting with just 2 words does not align with the initial condition of 125, and also involves an incorrect growth factor of 2.5. This is also **not** a correct representation of the problem.
3. **\( y = 2.5 \cdot (8)^{x} \)**:
- This equation grows much faster as \( x \) increases because it's based on \( 8^x \) rather than an exponential growth that is doubling. This is **not** a valid model for the AI's vocabulary growth.
4. **\( y = 2 \cdot (2)^{x} \)**:
- This equation represents exponential growth based on 2, but again starting with just 2 words does not align with the initial condition of 125. Thus, it's **not** suitable as a model for this specific case.
### Conclusion:
None of the given equations correctly model the AI's vocabulary growth based on the problem statement, which starts from 125 words and doubles that amount every 8 hours. The correct model, as previously stated, is:
\[
y = 125 \cdot 2^{(x/8)}
\]
For these equations to be viable substitutions, they would need to meet the initial vocabulary and growth rate specified, which none of them do.
