To subtract the complex numbers \(-5i\) and \(-16i\), we perform the following calculation:
\[
-5i - (-16i) = -5i + 16i
\]
Combining the imaginary parts:
\[
(-5 + 16)i = 11i
\]
So, the result is:
\[
11i
\]
Therefore, the correct response is \(11i\).
\[
-5i - (-16i) = -5i + 16i
\]
Combining the imaginary parts:
\[
(-5 + 16)i = 11i
\]
So, the result is:
\[
11i
\]
Therefore, the correct response is \(11i\).
