(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的16次方)+1/2的31次方等于多少
(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的16次方)+1/2的31次
=(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的16次方)/(1-1/2)+1/2的31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)(1+1/2的16次方)/(1-1/2)+1/2的31次方
=.
=(1-1/2的16次方)(1+1/2的16次方)/(1-1/2)+1/2的31次方
=(1-1/2的32次方)/(1/2)+1/2的31次方
=2-1/2的31次方+1/2的31次方
=2
