What is this equation formally? Having fun with the calculator, I realized that :
(a^c) and (a^b)
with c > b and c > 4 and b = 2
a^c / a^b = a^(c-2)

So, for example:
3^5 / 3^2 = 27 is same that 3^(5-2) => 27
I know it's basic, but how is this happening?
What is this formally called? I realized thinking "How often is this greater than this other"
I think it's "exponential growth"

A fraction with five factors equal to $3$ in the numerator, and two factors $3$ can be simplified by the elementary rules on fractions.
