To determine the type of number resulting from the product of \(\sqrt{36}\) and \(1212\), we first calculate \(\sqrt{36}\).
\[ \sqrt{36} = 6 \]
Next, we find the product:
\[ 6 \times 1212 = 7272 \]
Now, we analyze the result, \(7272\). It is a whole number, which means it is a type of rational number.
Since \(7272\) is rational (it can be expressed as \(\frac{7272}{1}\)), we conclude that the product of \(\sqrt{36}\) and \(1212\) is a rational number.
Thus, the answer is:
rational
