答

14.8×6.3-6.3×6.5＋8.3×3.7-------提取公因式6.3
=6.3*(14.8-6.5)+8.3*3.7
=6.3*8.3+8.3*3.7-----提取公因式8.3
=8.3*(6.3+3.7)
=8.3*10
=83

答

提取公因数
14.8×6.3-6.3×6.5＋8.3×3.7=6.3(14.8-6.5) +8.3×3.7=6.3×8.3+8.3×3.7=8.3(6.3+3.7)=8.3x10=83

答

14.8×6.3-6.3×6.5+8.3×3.7
=(14.8-6.5)×6.3+8.3×3.7
=8.3×6.3+8.3×3.7
=8.3×(6.3+3.7)
=8.3×10
=83
