128√e480

To simplify the expression \( 128\sqrt{e^{480}} \), we can use the properties of exponents and square roots.

First, we know that:

\[ \sqrt{e^{480}} = e^{480/2} = e^{240} \]

So, the expression becomes:

\[ 128\sqrt{e^{480}} = 128 e^{240} \]

Thus, the simplified form of the expression is:

\[ 128 e^{240} \]
