#(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#
