0.54x3.6+5.4x0.64=?

0.54x3.6+5.4x0.64=?
0.54x3.6+5.4x0.64=?

0.54x3.6+5.4x0.64=?
原式
=(0.01*54)*(0.1*36)+(0.1*54)*(0.01*64)
=0.01*0.1*54*(36+64)
=0.01*0.1*54*100
=0.1*54
=5.4

0.54x3.6+5.4x0.64
=0.54x3.6+0.54x6.4
=0.54x(3.6+6.4)
=0.54x10
=5.4

0.54x3.6+5.4x0.64
=5.4x0.36+5.4x0.64
=5.4x(0.36+0.64)
=5.4

原式=5.4×0.36+5.4×0.64
=5.4×(0.36+0.64)
=5.4×1
=5.4
