你好:

89.3×43+38×89.3+893×1.9
=89.3×43+38×89.3+89.3×19
=89.3×(43+38+19)
=89.3×100
=8930

10.01×101-10.01
=10.01×(101-1)
=10.01×100
=1001

89.3×43+38×89.3+893×1.9 10.01×101-10.01

= 89.3×43+38×89.3+89.3×19 = 10.01×101-10.01×1
=89.3×(43+38+19) =10.01×(101-1)
=89.3×(42+38+1+19) =10.01×100
=89.3×(80+20) = 1001
=89.3×100
=8930
