9.9×7.6=(10-0.1)*7.6 =76-0.76 =75.24 0.99+9.9×9.9-900% =0.99*1+0.99*99-9=0.99*(1+99)-9=99-9=90
9.9×7.6=(10-0.1)×7.6=10×7.6-0.1×7.6=76-0.76=75.24 0.99+9.9×9.9-900%=0.99+0.99×99-9=0.99×(1+99)-9=99-9=90

(25X4)x(100-5)X4=100x(100x4-5x4)=100x380=38000
25X95X16=25X95X4X4=100X380=38000
25×95×16=25×4×4 ×95=100×4×95=400×95=38000 请相信我
25×4×4×(100—5)=100×4×(100-5)=400×100 — 400 ×5
7600
把16变成4×4.把95变为(100-5)即可。答案为38000。谢谢采纳!
拆成25×4×4×95
