问题描述：
100.37×3.4+1.7×109.26简算
答
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
答
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
答
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
答
=200.74x1.7+1.7x09.26
=(200.74+109.26)x1.7
=310x1.7
=300x1.7+10x1.7
=510+17
=527
答
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
