3.7x5.4+0.37x46简便运算

3.7x5.4+0.37x46 =3.7x5.4+3.7x4.6 =3.7x(5.4+4.6) =3.7x10 =37

3.7*(5.4+4.6)=3.7*10=37

题中少了一个加号。 4.6×3.7+46×0.63 =46×0.37+46×0.63 =46×(0.37+0.63) =46×1 =46

原式 =3.7x5.4+0.37x46 =3.7x5.4+3.7x4.6 =3.7x(5.4+4.6) =3.7x10 =37 供参考。

54x3.7+46x3.7 =3.7×(54+46) =3.7×100 =370元

原式 =46.5x(3.7+7.3-1) =46.5x10 =465

46*57+23*86 =46*57+46*43 =46*(57+43) =46*100 =4600 希望我的回答能对你有帮助。

解:46X57十23X86 =46X57十23X(2X43) =46X57十46X43 =46X(57十43) =46X100 =4600

14.8x6.3+46.5x4.5+8.3x3.7+0.465x550-6.3x6.5 =14.8x6.3-6.3x6.5+46.5x4.5+46.5x5.5+8.3x3.7 =6.3x(14.8-6.5)+46.5x(4.5+5.5)+8.3x3.7 =6.3x8.3+8.3x3.7+46.5x10 =8.3x(6.3+3.7)+465 =8.3x10+465 =83+465 =548

解:原式=4.6x2.7+46x0.73 =4.6x2.7+4.6x10x0.73 =4.6x2.7+4.6x7.3 =4.6x(2.7+7.3) =4.6x10 =46 答:答案是46.
