Answer
Identity Property of Multiplication
Work Step by Step
Note that:
$\dfrac{\sqrt2}{\sqrt2} = 1$
and
$\dfrac{1}{\sqrt2} = \dfrac{2}{\sqrt2}$
RECALL:
The Identity Property of Multiplication states that for any real number $a$, $a \cdot 1 = a$.
With $a=\dfrac{1}{\sqrt2}$, the given expression illustrates the Identity Property of Multiplication.
