10^n/2(10^m-1+10^m+1)/10^m(10^n/2+10^2+n/2)
(10^m + 10.10^m)==> 10^m+ 100.10^m ==>(1+100).10^n ==> 101.10^m
10 10 10 10
10^m(10^n/2+10^2+n/2)==> 10^m(10^n/2+100.10^n/2) ==>10^m[(1+100)10^n/2]
10^m[101.10^n/2] ==> 101.10^m.10^n/2
10^n/2(10^m-1+10^m+1)
10^m(10^n/2+10^2+n/2)
10^n/2(101.10^m)
10 = 101.10^m.10^n/2 . 1
101.10^m.10^n/2 10 101.10^m.10^n/2
==> 1 ou 10^-1 ou 0,1
10
