Answer
Distributive Property
Work Step by Step
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.
