Calculate or simplify the expression $$ \sqrt{50} $$.
Calculate the value by following steps:
- step0: Calculate:
  $$\sqrt{50}$$
- step1: Write as a product:
  $$\sqrt{25	imes 2}$$
- step2: Write in exponential form:
  $$\sqrt{5^{2}	imes 2}$$
- step3: Use the properties of radicals:
  $$\sqrt{5^{2}}	imes \sqrt{2}$$
- step4: Simplify the root:
  $$5\sqrt{2}$$
The square root of 50 can be simplified as $$ \sqrt{50} = 5\sqrt{2} $$.

Therefore, the correct choice is:
A. $$ \sqrt{50} = 5\sqrt{2} $$
$$ \sqrt{50} = 5\sqrt{2} $$
