中括号括号一点八减零点六括号除以方块加二点五种括号乘以零点四等于三点式求方快多少

【(1.8-0.6)/()+2.5】*0.4=3.4

等于负九,你是对哒٩(๑^o^๑)&am

10.8÷【(5.2-1.6)×0.3】 =10.8÷【3.6×0.3】 =10.8÷1.08

8x126-8 =(126-1)x8 =125X8 =1000

题目输入不完整。 判断的依据是系数≠0,常数是0。函数式符合y=kx(k≠0)的形式。

括号五又九分之五减零点八加二又九分四括号乘括号七点六除与五分之四加二又五分之二乘一点二五括号外 &

35.35+(2.8-0.8)÷80% =35.35+2÷0.8 =35.35+2.5 =37

分时计算 2/3-(5/12+1/18) =2/3-5/12-1/18 =24/36-15/3

解:原式=-1/3*(1/4+4+6+9)=-1/3*77/4=-12/77。

5/8-(3/8+1/5) =5/8-3/8-1/5 =2/8-1/5 =1/4-1/5 =
