5.8*9.9+0.58 怎么简便

=5.8×9.9+5.8×0.1 =5.8×(9.9+0.1) =5.8×10 =58

=5.8×9.9+5.8×0.1 =5.8x(9.9+0.1) =5.8X10 =58

5.8x9.28÷0.58 =5.8÷0.58x9.28 =10x9.28 =92.8

=5.8×9+5.8×1 =5.8×(9+1) =5.8×10 =58

5.8×9.9+5.8 =5.8×(9.9+1) =5.8×10.1 =58.58

5.8x9.9+0.58 =5.8x9.9+5.8x0.1 =5.8x(9.9+0.1) =5.8x10 =58

5.8*9.9 =5.8*(10-0.1) =5.8*10-5.8*0.1 =58-0.58 =57.42

原式=3.8×0.64+6.2×0.64 =(3.8+6.2)×0.64 =10×0.64 =6.4

5.8x9.9+0.58 =5.8×9.9+5.8×0.1 =5.8×(9.9+0.1) =5.8×10 =58

解: 5.8*9.9+5.8 =5.8*9.9+5.8*1 =5.8*(9.9+1) =5.8*10.9 =63.22
