简便计算0.825*1.7+8.25*0.83
简便计算0.825*1.7+8.25*0.83

简便计算0.825*1.7+8.25*0.83
0.825*1.7+8.25*0.83
=8.25x0.17+8.25x0.83
=8.25x(0.17+0.83)
=8.25x1
=8.25

0.825×1.7+8.25×0.83
=0.825×1.7+0.825×8.3
=0.825×(1.7+8.3)
=0.825×10
=8.25

0.825*1.7+8.25*0.83
=8.25*0.17+8.25*0.83
=8.25*(0.17+0.83)
=8.25*1
=8.25

0.825*1.7+8.25*0.83
=0.825*1.7+0.825*8.3
=0.825*(1.7+8.3)
=0.825*10
=8.25

原式=0.825*1.7+0.825*8.3=0.825（1.7+8.3）=0.825*10=8.25
