x10.1

我发现10和0.1差了100倍!

原式 =13x(10+0.1) =13x10+13x0.1 =130+1.3 =131.3

=6.9×10+6.9×0.1 =69.69

73x10.1+27x10.1 =10.1x(73+27) =10.1x100 =1010 2.8x3.6+1.4x2.8 =2.8x(3.6+1.4) =2.8x5 =14

8.5x10+8.5x0.1

=53×10+53×0.1 =530+5.3 =535.3

5.7x(10+0.1) =5.7x10+5.7x0.1 =57+0.57 =57.57

10·01x10·1-1·001 =1.001X(101-1) =1.001X100 =100.1

1.1X10.1一1.1 =1.1X(10.1-1) =1.1X9.1 =(1+0.1)X9.1 =1X9.1+0.1X9.1 =9.1+0.91 =10.01

1.35×10.1 =1.35×(10+0.1) =1.35×10+1.35×0.1 =13.5+0.135 =13.635 你好,本题以解答,如果满意,请点右上角“采纳答案”,支持一下。
