4÷[(1.25+0.45)×23]=4÷[(1.25+0.45)×23]=4÷[(1.25+0.45)×23]=4÷[(1.25+0.45)×23]=4/(1.7x23)=4/39.1=40/391
4÷[(1.25+0.45)×23]=
4÷[(1.25+0.45)×23]=
4÷[(1.25+0.45)×23]=
4÷[(1.25+0.45)×23]
= 4 /( 1.7 x 23)
= 4 / 39.1
= 40 /391
4÷[(1.25+0.45)×23]=
7/15÷[1.25-(2/5+1/4)] 能简便就简便
[51 -(18 3/4 - 1÷ 8/15 )× 1 23/25]÷ 0.62
[(2/3-1/4)÷5/6+4/5]X5/11
若[1+3+5+…+(2x-1)]÷{[1÷(1×2)]+[1÷(2×3)]+…+[1÷x(x+1)]}=110
[(x-15)÷4-六分之一]×10=100 谢

函数f(x)=-x2+2x在区间[-3,4]最小值
2012贵州先化简1/x+1-3-x/x2-6x+91/(x+1)-[(3-x)/(x^2-6x+9)]÷[(x^2+x)/(x-3)]=1/(x+1)+[(x-3)/(x-3)^2][(x-3)/(x^2+x)]=1/(x+1)+1/(x^2+x)=1/(x+1
已知函数f(x)=x+1÷x ;用函数单调性定义证明f(x)在[1,2]上是增函数.
简便运算,3-5/8÷25/28-3/10…二、4/5×[13/16÷(3/4+1/3)]
864÷[(27-23)×12]这个怎么做一定要将算式列出来.
解方程[(x的平方×3.14)÷4]+2x=14.28
y=[(1+tanx)/cos²x]/(cos2x+sin2x)的定义域为(0,π/4),则函数的值域为多少
先化简,再求值[(a-3)/(2a-4) ]÷[(5/(a-2))-a-2],其中a=(√3)-3
[1-7分之6×(4-13分之10)×2又6分之1] ÷[(1-6分之5)×(1+5分之1)]
解方程[(a²+a-6)/12][(a-1)/(a+2)]=1
