0.9+（0.9-0.9）*0.9-0.9
=0.9+0-0.9 = 0
2.37-1.75+1.63-2.25
= 2.37+1.63-2.25-1.75
= 4 - 4 = 0
0.125*0.25*0.5*64
= 0.5^3 * 0.5^2 * 0.5 * 2^6
= 0.5^(3+2+1) * 2^6
= (0.5 * 2)^6 = 1追问^是什么意思
=0.9+0-0.9 = 0
2.37-1.75+1.63-2.25
= 2.37+1.63-2.25-1.75
= 4 - 4 = 0
0.125*0.25*0.5*64
= 0.5^3 * 0.5^2 * 0.5 * 2^6
= 0.5^(3+2+1) * 2^6
= (0.5 * 2)^6 = 1追问^是什么意思

一. =0
二. =2.37+1.63-(1.75+2.25) =4-4 = 0
三. =0.125*8*0.25*4*0.5*2 =1*1*1=1
二. =2.37+1.63-(1.75+2.25) =4-4 = 0
三. =0.125*8*0.25*4*0.5*2 =1*1*1=1
