i have a a and the same as a(12);

then it is equal to a(1×(12))

according to the identities ((an)k=a(nk)=a(n×k)) it is the same as a(1(12));

in this case it is the same as a1=a1;

a1=a;

SO: I have proven a false statement a=a;

 

could you help me understand the problem?

The product of a and a12 is a12×a12=a12+12=a1=a

.

The general rule here is an×ak=an+k
