how would you write (11/20)^-6 as a single power... don't evaluate.
it is already written as a single power. However, if you want a positive power, then
(11/20)^-6 = 1/(11/20)^6 = (20/11)^6
To write (11/20)^-6 as a single power, you can apply the rule of exponents that states: (a/b)^-n = (b/a)^n.
So, let's apply this rule to (11/20)^-6:
(11/20)^-6 = (20/11)^6
Hence, (11/20)^-6 can be written as (20/11)^6.
