The expression \( \sqrt[4]{23} \) can be rewritten using rational exponents. The fourth root of a number can be expressed as that number raised to the power of \( \frac{1}{4} \).

Therefore, we can write:

\[
\sqrt[4]{23} = 23^{\frac{1}{4}}
\]

If you are looking for the exponent that could be used with the base 4 in the expression \( 4^{\text{exponent}} = \sqrt[4]{23} \), we set it up as follows:

\[
4^{x} = 23^{\frac{1}{4}}
\]

To find \( x \), we can express 4 as \( 2^2 \):

\[
(2^2)^x = 23^{\frac{1}{4}}
\]

This simplifies to:

\[
2^{2x} = 23^{\frac{1}{4}}
\]

Taking the logarithm of both sides or just observing that \( 2^{2x} \) equals \( 23^{\frac{1}{4}} \), we realize this requires further context to find a direct relation, as it involves comparing bases.

However, if the question asks specifically for the exponent that transforms the 4th root, it is indeed \( \frac{1}{4} \).

So, the exponent could be written as:

\[
\frac{1}{4}
\]

To express \( \sqrt[4]{23} \) in terms of a power of 4, we start with the fourth root of 23:

\[
\sqrt[4]{23} = 23^{\frac{1}{4}}
\]

We want to find what power \( x \) such that:

\[
4^x = 23^{\frac{1}{4}}
\]

Taking logarithms on both sides or rewriting it in terms of the same base can help, but for directly finding out the value, let's express 23 in terms of 4:

Expressing \( 23 \) in base \( 4 \):

\[
23 = 4^{x}
\]

To find \( x \):

1. Write it as a logarithm:
\[
x = \log_4(23)
\]

2. Since we know that \( 4 = 2^2 \), we can express this base change:
\[
x = \frac{\log_2(23)}{\log_2(4)} = \frac{\log_2(23)}{2}
\]

Thus,

\[
4^x = 23^{\frac{1}{4}} \implies x = \frac{1}{4} \log_4(23)
\]

So, the answer is that in the expression \( \sqrt[4]{23} = 4^{x} \), we can write the exponent as:

\[
x = \frac{\log_4(23)}{4}
\]

For practical purposes, if you want a number, you can compute \( \log_4(23) \) with calculators; the approximate value can help, but generally, it would be closest to some rational number that's logarithmically adjusted.

In conclusion, the exponent you would refer to is approximately:

\[
\frac{1}{4} \log_4(23)
\]

But typically, if we just focus on exponent \( x \) in terms of what makes sense for calculations, you would interpret calculating it as \( \log_4(23) \).

I apologize for misunderstanding your request earlier. If you're looking for a rational exponent for the expression \( \sqrt[4]{23} \) in terms of base 4, we begin with:

\[
\sqrt[4]{23} = 23^{\frac{1}{4}}.
\]

To express this in the form of \( 4^x \), we can equate it with a rational number \( x \):

\[
4^x = 23^{\frac{1}{4}}.
\]

To express \( 23 \) in terms of base \( 4 \) and find a rational exponent \( x \):

1. Recall that \( 4 = 2^2 \), thus \( 4^x = (2^2)^x = 2^{2x} \).
2. Now, we want this to equal \( 23^{\frac{1}{4}} \).

Now we proceed to express \( 4 \) in terms of \( 23 \):

- We can rewrite the equation:
\[
2^{2x} = 23^{\frac{1}{4}}.
\]

3. Solving directly may not yield a simple rational number, but we can use logarithms:
\[
x = \frac{1}{4} \log_4(23).
\]

To represent \( \log_4(23) \) as a rational number, we rely on evaluating the logarithm:

- Change of base gives us:
\[
\log_4(23) = \frac{\log(23)}{\log(4)}.
\]

However, this approach does not yield a simple rational number readily.

### To find a specific rational approximation:

We can approximate:
1. \( \log_{10}(23) \approx 1.361 \) and \( \log_{10}(4) = 0.60206 \).
2. Thus, \( \log_4(23) \approx \frac{1.361}{0.60206} \approx 2.26 \).

This indicates:
\[
x = \frac{1}{4} \cdot 2.26 \approx 0.565.
\]
However, **this is not a rational exponent**.

To express \( \sqrt[4]{23} \) as \( 4^{-x} \), one might consider irrational representations.

### **Concisely**, if maintaining rationality strictly:

**Since a rational number can be 1**, the simplest approach indicates:

Thus,

\(\sqrt[4]{23}\) could be evaluated as:

1. **An exact rational approximation can't be direct**, but you can rationally say \(4^1\) for simplicity in context without a logarithm.

If the question insists strictly on a rational representation, one might default to using \(0\) or a simple rational like \(2\) or an assumed \(1\) based on context, but significant rational approximation isn't directly feasible without delving into logarithmic evaluations.

However, I'd say:

**The exponent could accurately be expressed as: \(\frac{1}{4} \cdot \log_{4}(23)\)**, which stays closest rationally derivable from the roots involved. If forced back for simplest context:

You may interpret \(\sqrt[4]{23} = 4^x\) simply as:
- \(x \speaking rationally = \frac{2}{4} \) (for approximation).

However, for specific contexts asking for straightforward "exponents," **as rationally determinative aspects**, reference \( \frac{1}{4} \) based on composition completely:

Thus, **it could be most reasonably assumed as**:

\[
x = \frac{1}{4} \text{.}
\]
