37x8x9+6.3x7.2如何简便计算？

Answer 1

您好，很高兴为您解答。

根据题意，

原式=370×7.2+6.3×7.2

=7.2×（370+6.3）

=7.2×376.3

=2709.36

希望对您有帮助，祝您幸福快乐每一天！

Answer 2

37x8x9+6.3x7.2，简便计算就是
=37x72+0.63x72
=72x(37+0.63)
=72x37.63
我觉得你的题目错了。应该是前面37变成3.7。而后面的6.3是63。这样就可以简便了
3.7x8x9+63x7.2
=3.7x72+6.3x72
=72x(3.7+6.3)
=72x10
=720

Answer 3

37x8x9＋6.3x7.2

＝37x72＋6.3x7.2

＝72x（37+0.63）

＝72x37.63

＝70x37.63+2x37.63

＝2634.1+75.26

＝2709.36

Answer 4

37*8*9+6.3*7.2
=37*7.2*10+6.3*7.2
=（370+6.3）*7.2
=376.3*7.2
=2709.36

Answer 5

37x8x9+6.3x7.2
=37ⅹ72+6.3ⅹ7.2
=370ⅹ7.2+6.3ⅹ7.2
=7.2x(370+6.3)
=7.2╳376.3
=(7+0.2)x376.3
=2634.1+75.26
=2709.36
