... Someone could help me with this. I need to prove that(adsbygoogle = window.adsbygoogle || []).push({});

Finitedecimal = p/(2^a)(5^b) where either a or b could be 0 and p is a prime.

Basically this formula comes from...

Finitedecimal = (a1/10)+(a2/10^2)+....+(an/10^n)

What is a here? and how to prove it? Please help I am stuck
