100.37×3.4+1.7×109.26简算

100.37×3.4+1.7×109.26简算
100.37×3.4+1.7×109.26简算

100.37×3.4+1.7×109.26简算
原式
=200.74×1.7+1.7×109.26
=1.7×(200.74+109.26)
=1.7×310
=1.7×(300+10)
=1.7×300+1.7×10
=510+17
=527

=200.74x1.7+1.7x09.26
=(200.74+109.26)x1.7
=310x1.7
=300x1.7+10x1.7
=510+17
=527

100.37*3.4+1.7*109.26=200.74*1.7+1.7*109.26=1.7*(200.74+109.26)=1.7*310=1.7*300+1.7*10=510+17=527

100.37×3.4+1.7×109.26
=100.37x1.7x2+1.7x109.26
=1.7x(100.37x2+109.26)
=1.7x(200.74+109.26)
=1.7x310
=527

原式=100.37*2*1.7+1.7*109.26=1.7*(200.74+109.26)=1.7*310=1.7*(300+10)=527
