(1+1/2)×(1+1/2的2次方)×(1+1/2的4次方)×(1+1/2的8次方)+1/2的15次方
=(1-1/2)(1+1/2)×(1+1/2的2次方)×(1+1/2的4次方)×(1+1/2的8次方)/(1-1/2)+1/2的15次方
=(1-1/2的2次方)×(1+1/2的2次方)×(1+1/2的4次方)×(1+1/2的8次方)×2+1/2的15次方
=(1-1/2的4次方)×(1+1/2的4次方)×(1+1/2的8次方)×2+1/2的15次方
=(1-1/2的8次方)×(1+1/2的8次方)×2+1/2的15次方
=(1-1/2的16次方)×2+1/2的15次方
=2-1/2的15次方+1/2的15次方
=2
