#1/(a^2)#

Explanation:

Whenever there's a negative value in the exponent... it means.... inverse it
#2^(-2)=2^(-2)/1=1/(2^2)#
It is taken like that because you can take it as one big inverse proportion or something....
#10^2=10xx10#
#10^1=10#
#10^0=10/10=1#
#10^-1=10/100=1/10#
You see?.... Hope you understood it well
