Which of the following is equal to the above expression?

$\large A = 2^{5555}, \qquad B = 3^{3333}, \qquad C = 6^{2222}$

What is the order of these numbers from smallest to largest?

If $$2^x = 3^y = 6,$$ then which of the following statements is true?

Find the sum of all integer solutions to the equation

If you have a piece of paper that is $$0.1\text{ mm}$$ thick, then how many times will you have to fold it in half in order for it to become tall enough to reach the moon?

Note: The distance from the earth to the moon is $$384400\text{ km}$$.

You have to round off the answer that you are getting to get the answer that you will enter in the answer box.
