If I have the question what is 7^3^-2 and I do
7^3 = 343
343^-2 = .0000084
If I try to answer that by using the rule for raising a power to a power then I get:
7^3^-2
= 7^(3*-2)
= 7^-6
= 1/7^6 = .0000084
So I am pretty sure that I understand this correctly and yet if I go to any number of calculators, online, on my phone and pysical and enter
7^3^-2 I get the really confusing answer of 1.241365817.
If I enter it into the calculator as (7^3)^-2 then I get .0000084
So what is the difference between (7^3)^-2 and 7^3^-2?
