To simplify \( 54\sqrt{3} \), we can express it in a clearer format if needed, but it is already in a simplified form.
If you're asking to express it in terms of cubic roots or other roots, we can explore other notations, but generally, \( 54\sqrt{3} \) does not simplify further in a conventional sense.
The expression \( 54\sqrt{3} \) can also be factored as:
\[ 54\sqrt{3} = 54 \cdot 3^{1/2} = 54 \cdot 3^{3/6} \]
However, this doesn't necessarily simplify to anything more recognizable.
If you would like to compute a numerical approximation, \( 54\sqrt{3} \approx 93.5307 \), but the simplified form remains \( 54\sqrt{3} \).
Please clarify if you are looking for a specific type of simplification!
