原式
=(1+2^(1/32))(1+2^(1/16))(1+2^(1/8))(1+2^(1/4))(1+2^(1/2))
=[(1+2^(1/32))(1+2^(1/16))(1+2^(1/8))(1+2^(1/4))(1+2^(1/2))*((1-2^(1/32))]/(1-2^(1/32))
=[(1-2^(1/16))(1+2^(1/16))(1+2^(1/8))(1+2^(1/4))(1+2^(1/2))]/(1-2^(1/32))
=[(1-2^(1/8))(1+2^(1/8))(1+2^(1/4))(1+2^(1/2))]/(1-2^(1/32))
=[(1-2^(1/4))(1+2^(1/4))(1+2^(1/2))]/(1-2^(1/32))
=[(1-2^(1/2))(1+2^(1/2))]/(1-2^(1/32))
=(1-2)/(1-2^(1/32))
=-1/(1-2^(1/32))
