(X-65000)/X=0.11,求X=多少,
(X-65000)/X=0.11,求X=多少,
(X-65000)/X=0.11,求X=多少,
有啊：
(X-65000)/X=0.11
X-65000=0.11X
X-0.11X=65000
0.89X=65000
X=65000/0.89
X=6500000/89
有啊
(1)
原式
=(0.25)^23×2^46×2×2
=(0.25)^23×(2^2)^23×4
=(0.25×2^2)^23×4
=1^23×4
=4
(2)
原式
= -8×(-0.125)^2000×(-8)^2000×(-8)
= 64×(-0.125×(-8))^2000
= 64×1^2000
= 64
650分之89把
yt帝国大厦
(X-65000)/X=0.11
X-65000=0.11X (x不等于0)
100X-6500000=11X
X=6500000/89
(X - 65000) / X = 0.11
X- 65000 = 0.11X
0.89X = 65000
X = 73033.71
