问题：指数计算:(1+2负1/8次方)(1+2负1/4次方)(1+2负 
计算:(1+2负1/8次方)(1+2负1/4次方)(1+2负1/2次方)的值
回答：(1+2负1/8次方)(1+2负1/4次方)(1+2负1/2次方)=(1-2负1/8次方)(1+2负1/8次方)(1+2负1/4次方)(1+2负1/2次方)/(1-2负1/8次方).
(1-2负1/8次方)(1+2负1/8次方)=1-2负1/4次方;(1-2负1/4次方)(1+2负1/4次方)=1-2负1/2次方;(1-2负1/2次方)(1+2负1/2次方)=1-2
所以(1-2负1/8次方)(1+2负1/8次方)(1+2负1/4次方)(1+2负1/2次方)/(1-2负1/8次方)=-1/(1-2负1/8次方)
