simplify

   3^n x 9^n+1

   3^n-1 x 9^n-1

formula used here is:

    a^m x a^n  = a^m+n

   a^m / a^n  = a^m-n

so,

    3^n x 9 ^ n+1    =    3^[n -(n-1)]  x 9 ^ [n+1 - (n-1)]

   3^n-1 x 9^n-1      

                               =    3^1 x 9 ^2

                               =     3 x 81

                               =  243
