Let's say that your problem is

The "4" would be your index of the exponent in the and the "6" would be your base in the problem (if that makes any sense to you)
Now we have to write "

" which is (6)(6)(6)(6) = 1,296
To make it "simpler" you 6(6) = 36 = 6(6) = 36 ← (again) So, 36(36) = 1,296
Does this come to mind to you?
