To perform the operation \(\sqrt{6} \cdot \sqrt{8}\), we first use the property of square roots that states \(\sqrt{a} \cdot \sqrt{b} = \sqrt{a \cdot b}\).

So, we have:

\[ \sqrt{6} \cdot \sqrt{8} = \sqrt{6 \cdot 8} \]

Calculating the product inside the square root:

\[ 6 \cdot 8 = 48 \]

Thus, we have:

\[ \sqrt{6} \cdot \sqrt{8} = \sqrt{48} \]

Next, we simplify \(\sqrt{48}\). We can factor 48 into its prime factors:

\[ 48 = 16 \cdot 3 = 4^2 \cdot 3 \]

Now we can take the square root:

\[ \sqrt{48} = \sqrt{16 \cdot 3} = \sqrt{16} \cdot \sqrt{3} = 4\sqrt{3} \]

Therefore, the exact simplified answer is:

\[ \sqrt{6} \cdot \sqrt{8} = 4\sqrt{3} \]
