Ở dòng 11 chữ số thứ 34 (hình như thế

ở dòng 23,số 26 từ trái sang phải

TH1 x>y

Ta có (xy+1)2=x^2.y^2+2xy+1>x2y2+x−y>x^2.y^2

Do đó loại vì x^2.y^2 làSCP.

TH2 x<y cm tương tự, loại.

Do đó x=y.

ta có

S=1+ 1/2 +1/2^2 +..+1/2^100

=> S/2 -S=1/2+ 1/2^2+...+1/2^101-1-1/2-...1/2^100

=> -S/2=1/2^101-1

=> -S/2=(1-2^101)/2^101

=> S=-2*(1-2^101)/2^101

=> S=(2^101-1)/2^100
