2.009x43+20.9+200·9x0·28
=2.009×43+2.09×10+2.009×28
=2.009×(43+28)+(2.009+0.081)×10
=2.009×71+2.009×10+0.81
=2.009×(71+10)+0.81
=2.009×81+81×0.001
=81×(2.009+0.001)
=81×2.01
=162.81
=2.009×43+2.09×10+2.009×28
=2.009×(43+28)+(2.009+0.081)×10
=2.009×71+2.009×10+0.81
=2.009×(71+10)+0.81
=2.009×81+81×0.001
=81×(2.009+0.001)
