To simplify the expression \( x^{16} \cdot x^{16} \), we can use the property of exponents that states \( a^m \cdot a^n = a^{m+n} \).
Applying this to our expression:
\[ x^{16} \cdot x^{16} = x^{16+16} = x^{32} \]
Now, we need to express \( x^{32} \) in terms of the provided response options.
We can rewrite \( x^{32} \) as follows: \[ x^{32} = (x^2)^{16} = \sqrt[3]{x^{48}} = \sqrt{x^{32}} \]
However, we don't see an exact expression for \( x^{32} \) in the options given. Instead, let's verify each option to see which one can be simplified to \( x^{32} \):
- Option 1: \( \frac{1}{\sqrt[3]{\sqrt{x}}} \) does not correspond.
- Option 2: \( \sqrt{x} \) corresponds to \( x^{1/2} \).
- Option 3: \( \sqrt[36]{x} \) which corresponds to \( x^{1/36} \).
- Option 4: \( \sqrt[3]{x} \) corresponds to \( x^{1/3} \).
None of these match \( x^{32} \), indicating that this question likely seeks the equivalent of \( x^{32} \) under a different format, possibly not among the standard responses.
Thus, none of the provided expressions is equivalent to \( x^{16} \cdot x^{16} \). Could you please check if there might be additional expressions or a rephrasing needed?
