To sum \(3\sqrt{16}\) and \(4\sqrt{6}\), we first simplify each term:
1. For \(3\sqrt{16}\):
\[
\sqrt{16} = 4,
\]
so:
\[
3\sqrt{16} = 3 \times 4 = 12.
\]
2. For \(4\sqrt{6}\), it remains as \(4\sqrt{6}\) since \(6\) is not a perfect square and cannot be simplified further.
Now we can add the two results together:
\[
12 + 4\sqrt{6}.
\]
This expression, \(12 + 4\sqrt{6}\), is the sum of a rational number (12) and an irrational number (\(4\sqrt{6}\)).
Now, we need to determine if the overall result is rational or irrational.
A rational number is any number that can be expressed as the quotient of two integers. An irrational number cannot be expressed this way and has a non-repeating, non-terminating decimal expansion.
Since we have a rational number (12) and an irrational number (\(4\sqrt{6}\)), the sum of a rational and an irrational number is always irrational.
Thus, the final answer is:
\[
\text{The sum is } 12 + 4\sqrt{6}, \text{ which is irrational.}
\]
