ooh look the answer is C
what a shock
C, is the preferred answer by over 5  to 1

jim_thompson5910 · Answer

Why the answer is choice C
$$\Large \sqrt{1792} = \sqrt{256*7}$$
$$\Large \sqrt{1792} = \sqrt{256}*\sqrt{7}$$
$$\Large \sqrt{1792} = 16\sqrt{7}$$
notice how I factored 1792 into two numbers where one of the numbers are a perfect square (the largest perfect square factor possible)
Then I used the rule $\Large \sqrt{x*y} = \sqrt{x}*\sqrt{y}$
