Theory

$\frac{a}{b} = \frac{a}{b}$

A fraction where both numerator and denominator are square roots can be simplified by taking the square root of the entire fraction.

\frac{1 2}{3} = \frac{1 2}{3} = 4

This rule applies for all non-negative real numbers where the denominator is not

0,

and can be shown by rewriting the square roots as powers and using the Quotient of Powers Property.
