Dear tuanquang269,
This is Mike from Magoosh. :-) Unfortunately, my friend, there's an error in how you posted the question. The x on the right side of the equation need to be an exponent.

If 2 ÷ 2 ÷ 2 ÷ 2 ÷ 2 = 2^x, then x =

Unfortunately, I don't have the power to make this edit. Either you will have to make the change, or Bunuel will have to.

Does this make sense?
Mike :-)

Is it E?

\(2 ÷ 2 ÷ 2 ÷ 2 ÷ 2 = 2 * \frac{1}{2} * \frac{1}{2} * \frac{1}{2} * \frac{1}{2} = \frac{2}{2^4} = \frac{1}{2^3}\)
