14.8×6.3-6.3×6.5+8.3×3.7 的递等式计算,谢谢

14.8*6.3-6.3*6.5+8.3*3.7=6.3*(14.8-6.5+3.7)+2*3.7=6.3*12+2*3.7=6.3*10+2*(6.3+3.7)=63+20=83

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明白请采纳,有疑问请追问!有新问题请求助,谢谢!

=14.8*6.3-6.5*6.3+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*10.0=83.0

①415-176-24,=415-(176+24),=415-200,=215;②15*27-3000÷25,=405-120,=285;③8.29+3.7+0.71+6.3,=(8.29+0.71)+(3.7+6.3),=9+10,=19;④125*89*8,=125*8*89,=1000*89,=89000;⑤(324-285

14.8x6.3-6.3x6.5+8.3x3.7;=6.3x(14.8-6.5)+8.3x3.7;=6.3x8.3+8.3x3.7;=8.3x(6.3+3.7);=8.3x10;=83

原式=6.3*(14.8-6.5)+0.465*(450+550)+8.3*3.7 =6.3*8.3+0.465*1000+8.3*3.7 =(6.3+3.7)*8.3+465 =83+465 =548
