Answer: [tex]4\sqrt{3}[/tex] (choice A)
========================================
Work Shown:
[tex]\sqrt{48} = \sqrt{16*3}\\\\\sqrt{48} = \sqrt{16}*\sqrt{3}\\\\\sqrt{48} = 4\sqrt{3}[/tex]
The idea is to factor 48 such that one of the factors is the largest perfect square possible. So that's why we go with 48 = 16*3. Then we use the rule [tex]\sqrt{x*y} = \sqrt{x}*\sqrt{y}[/tex] to break up the root.
