Work Step by Step

Using the properties of radicals, the given expression, $ \dfrac{4\sqrt{3}}{\sqrt{12}} ,$ simplifies to \begin{array}{l}\require{cancel} 4\sqrt{\dfrac{3}{12}} \\\\= 4\sqrt{\dfrac{\cancel{3}}{\cancel{3}(4)}} \\\\= 4\sqrt{\dfrac{1}{4}} \\\\= 4\sqrt{\left(\dfrac{1}{2}\right)^2} \\\\= 4\left(\dfrac{1}{2}\right) \\\\= 2 .\end{array}
