    Math Question

    Simple question:

    Can an exponent have an exponent?

    For example, can you have 9^9^9?

    My Microsoft excel says yes.

        Not the way that you have it written (if I'm not mistaken). Though, the "powers rule" allows you to raise a power to a power. For example... (a^x)^y = a^(x*y). So (9^9)^9 = 9^81. Hence my comment "not the way you have it written."

        Somebody feel free to correct me. Been a few years since graduation so I'm a bit rusty. Here are some more rules that may apply to whatever you're working on...

          I would show it as x^(x^x)
          So 2^(2^2) = 2^4= 16

              The question came up when I read an article about the largest number you can make using three digits(numbers).

              Instinct is to go to 999, but the article showed that nine to the ninth power to the ninth power was actually the largest number.

              It was an interesting read.
