=3.75×(5.3+3.5)÷2.2 =3.75×(8.8÷2.2) =3.75×4 =15 9.6/4.8x(7.2+2.8) =9.6/4.8x10 =9.6/48 =0.2

5000×括号里面的2+3.75%乘以4 =5000x(2+0.0375)x4 =40750 5000×括号里面的2+3.75%乘以4 =5000x(2+0.0375x4) =10750 请采纳正确答案,你们只提问,不采纳正确答案,回答都没有劲!谢谢管理员推荐采纳!! 朋友,请【采纳答案】,您的采纳是我...

解: x(1+3.75%)(1+3.75%) =x(1+0.0375)(1+0.0375) =x(1.0375²) =1.07640625x

(31.4-3.75)÷2.5÷4 =27.65÷(2.5×4) =27.65÷10 =2.765

8.37+1.25-1.37+3.75 =(8.37-1.37)+(1.25+3.75) =7+5 =12 你好,本题已解答,如果满意 请点右下角“采纳答案”。
