100(X-1)的平方=144 怎么计算?
100(X-1)的平方=144 怎么计算?

100(X-1)的平方=144 怎么计算?
(x-1)²=1.44
x-1=±1.2
x=-0.2,x=2.2

100(X-1)的平方=144
(x-1)²=1.44
x-1=±1.2
x1= -0.2 x2= 2.2

100(X-1)的平方=144
(X-1)的平方=1.44
x-1=±1.2
x=2.2 x=-0.2

144开方为12,则两边同时开方,得到:x-1=0.12,则x=1.12
哦,看错了,(x-1)²=1.44
x-1=±1.2
x=-0.2,x=2.2

100(x-1)^2=144
(10(x-1))^2=12^2
10(x-1)=12, x=2.2
10(x-1)=-12, x=-0.2

100(x-1)^2=144
(x-1)^2=36/25
x-1=6/5或-6/5
x=11/5或x=-1/5

100(X-1)方=144
(X-1)方=1.44
X-1=正负1.44
x=2.44
或x=0.44

100(x-1)²=144
(x-1)²=144/100
x-1=根号下144/100
x-1=1.2
x=2.2
