To simplify the expression \( 3027\sqrt{-63\sqrt{} }\), we first need to address the term under the square root.

Given that \( -63 \) is under the square root, it can be expressed as:

\[ \sqrt{-63} = \sqrt{63} \cdot \sqrt{-1} = \sqrt{63} i \]

Next, \( \sqrt{63} \) can be simplified further:

\[ \sqrt{63} = \sqrt{9 \cdot 7} = \sqrt{9} \cdot \sqrt{7} = 3\sqrt{7} \]

Now, substituting this back into our expression, we have:

\[ \sqrt{-63} = 3\sqrt{7} i \]

Thus, the expression simplifies to:

\[ 3027 \cdot 3\sqrt{7} i = 9081\sqrt{7} i \]

Since this expression is a complex number, it's not one of the regular responses (−3, −15, 15, 3). If you're looking for a numerical answer involving only real numbers, we could say that the expression contains an imaginary component and cannot be simplified into just real numbers.
