(4a^2)/a=4a

Explanation:

In our calculation there are two letters a, two same
variables. Because of that we can use the rule and just simply put numbers and variables from our calculation to equation

x^a/x^b=x^a-x^b => 4a^2-a^1

Now you just subtract 2-1 which is 1. So you keep one a. That means 4a^2-a^1=4a

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Rule of one: a^1 and a are same, we usually don't write ^1.
a^1=a
