# Question 9e5f7

An equation always has an '$=$' sign. Examples would be $x = 2$ or $a + b = 5$
$\sqrt{2} \cdot \sqrt{3}$ is a Numerical Expression, not an Equation.
We can simplify it using the identity color(blue)(sqrta*sqrtb = sqrt(ab)#
$\sqrt{2} \cdot \sqrt{3} = \sqrt{2 \cdot 3} = \sqrt{6} \approx 2.4949$
