To simplify \(\sqrt{28}\), let's start by breaking it down:
\[ \sqrt{28} = \sqrt{4 \cdot 7} \]
Now, we can apply the property of square roots that states \(\sqrt{a \cdot b} = \sqrt{a} \cdot \sqrt{b}\):
\[ \sqrt{28} = \sqrt{4} \cdot \sqrt{7} \]
Since we know that \(\sqrt{4} = 2\), we can simplify further:
\[ \sqrt{28} = 2 \cdot \sqrt{7} \]
Thus, the simplified form of \(\sqrt{28}\) is:
\[ 2\sqrt{7} \]
Therefore, the correct response is:
2\(\sqrt{7}\).
