Subtract 11 Square root 19 - 5 square root 9

Answer 1

To simplify \( 11 \sqrt{19} - 5 \sqrt{9} \), first, we can simplify \(\sqrt{9}\):

\[ \sqrt{9} = 3 \]

Now, substitute this back into the expression:

\[ 11 \sqrt{19} - 5 \sqrt{9} = 11 \sqrt{19} - 5 \cdot 3 \]

This simplifies to:

\[ 11 \sqrt{19} - 15 \]

Thus, the final answer is:

\[ 11 \sqrt{19} - 15 \]
