48×81÷(8×9)×5+16×4×(9×5)简算
48×81÷(8×9)×5+16×4×(9×5)简算
48×81÷(8×9)×5+16×4×(9×5)简算
48×81÷(8×9)×5+16×4×(9×5)
=48/8*81/9*5+16*4*5*9
=6*9*5+16*20*9
=30*9+320*9
=350*9
=3150
原式=48/8 *81/9 *5 +16*4*9*5=6*9+16*4*9*5=9*(6+16*20)=9*326=2934
用计算器行不?
=270*5+16*20*9
=
48*81/(8*9)*5+16*4*(9*5)
= (48/8)*(81/9)*5+16*4*(9*5)
= 6*9*5+16*4*9*5
= (6+16*4)*(9*5)
= (6+64)*45
= 70*45
= 3150
3150
48×81 ÷(8×9)×5+16×4×(9×5)
= (48/8)*(81/9)*5+(16*9)*(4*5)
=6*9*5+144*20
=270+2880
=3150
