2

$\sqrt{a} \cdot \sqrt{b} = \sqrt{a \cdot b}$ $sqrt(a) * sqrt(b) = sqrt(a*b)$

so in our case:

$\sqrt{2} \cdot \sqrt{2} = \sqrt{2 \cdot 2}$ $sqrt(2) * sqrt(2) = sqrt(2*2)$

which then simplifies into:

$\sqrt{4}$ $sqrt(4)$

which then can be further simplified into:

2

to double check this answer, $2 \cdot 2 = 4$ $2*2 = 4$ which is the same as $\sqrt{4}$ $sqrt(4)$
