Official Solution:

If $$x$$ is a positive number and $$2\sqrt{2}=\sqrt{\sqrt{x}-6}$$, then what is the value of $$x$$?

A. $$\frac{14}{\sqrt{2}}$$
B. $$14$$
C. $$169$$
D. $$196$$
E. $$225$$

Square both sides of the equation: $$8=\sqrt{x}-6$$;

Rearrange: $$\sqrt{x}=14$$;

Square again: $$x=196$$.
