## Thinking Mathematically (6th Edition)

RECALL: The distributive property states that for any real numbers $a, b,$ and $c$, $a(b+c) = a\cdot b+a \cdot c$ Notice that: $\sqrt3(\sqrt5 + \sqrt3) = (\sqrt3)(\sqrt5) + (\sqrt3)(\sqrt3) = \sqrt{15}+3$ Thus, the given expression illustrates the distributive property.
