    You could also write it as 5^1 x 5^-1 x 5^-1 x 5^-1 , then add the exponents and get 5 ^-2 . Thanks for keeping the brain engaged!!

      Or write it as 5/(5*5*5),
      putting everything which comes after a divide sign as a factor in the denominator of a single fraction.
      Then that equates to 5^1 / 5^3
      Then add (or subtract) the powers:
      1-3 = -2

    The answer is 1/25 but that answer isn't one of the choices. So, you need to figure out which one of the choices equals 1/25. That choice is 5^-2, or D. This teacher showed how to look at the choices and get to that answer in six steps....so beautifully concise. Thank you LKLogic...

    I teach Math Olympiads (prepare really) my 4th--5th grade students for these competitions here in California. I am barely able to understand basic calculus and trig...and that was really when I was in college with a tutor etc... Most kids that are in these competitions are not normal 100 i.q. humans like me (if I'm even that high). What you have to keep in mind is that many of the problems, at least the level of Math Olympiads for 4th through 6th grade, is structured in difficulty from relatively simple and direct to absurdly difficult; divided into a 5 problem competition. This problem would not have a multiple choice (I've never seen a multiple choice in the competition), but it would be the easiest problem; this is straight forward arithmetic. A more typical problem, that is difficult in this situation, is to ask the student to find the pattern and write the answer for 'n' divisions of the expression.

If they study well, they believe that they will have a better job and be more appreciated by society. In any case, they will be more confident than those who study poorly, although the real future does not necessarily depend only on this.

    I'm noticing that the symbol '÷' shows up in most of these math-parsing questions. The conclusion is that this is a stupid symbol to use, and that one should instead write proper fractions. Indeed, the two dots on either side of the line in the symbol '÷' shows where the sub-expressions should go. It is simply a kludge used on calculators because of their inherent limitations in data input.
    Therefore, I hereby declare all expressions using the symbol '÷' to be invalid anyway, and the correct answer to be 'undefined'.

    Where is the parentheses? Without brackets it is undefined because whatever be the step you used the answer must be the same

    I'm puzzeled by this. Repeated exponentiation is computed from the right, so 2^2^2^2=65536 and not 256 which you get if you compute from the left. But repeated division is computed from the left, why?😮

      Tower of exponents is a different thing altogether.
      5÷5÷5÷5 can be expressed as multiplication of fractions (÷ changes to × followed by the reciprocal).

      NO! You must divide from left to right, so 5÷5÷5÷5 = 1÷5÷5 =1/5 ÷ 5 = 1/25 = 5^(-2) I hope that helped
