求求各位大侠了,我是新人啊
(-0.5)+(9/2)+(-19/2)+9.75=?求求各位大侠了,我是新人啊
(-0.5)+(9/2)+(-19/2)+9.75
=-0.5+9/2-19/2+9.75
=(9.75-0.5)-(19/2-9/2)
=9.25-5
=4.25
(-0.5)-9/2-(-19/2)+9.75
(-0.5)+9/2+(-19/2)+9.75
(-0.5)+2分之9+(-2分之19)+9.75
(-0.5)+(9/4)+(-19/2)+(9.75) 怎么算

8/19-(8/19-2/9)
6.3×1/2÷(1.8+2.7×1/2) 0.56×(5/12-19/60+2.375)÷0.5(4/9×2.4+1.6×4/19)×4/5
x+y+z=19求函数u=(x^2+4)^0.5+(y^2+9)^0.5+(z^2+16)^0.5的最小值(0.5为开二次方) 最好用柯西不等式解答
数学计算题;(-0.5)+(9/2)+(-19/2)+9.75=?(-1/2)+(-2/5)+(3/2)+(18/5)+(39/5)=?
(-0.5)+9/4+(-19/2)+9.25=?;(-4/5)+6=?
数列题 0.5,2,9/2,8,
(19 4/9+9 4/19)÷(2 7/9+1 6/19)
(9又3分之2)/(-0.5)-21又2分之1*4分之3+12又3分之2/(-6分之19)等于多少
9又3/4-15*19-2/19简便算法
1( )9( )9( )2乘1( )9( )9( )2乘19( )9( )2等于1992 ( )应填几
[1()9()9()2]×[1()9()9()2]×[19()9()2]=1992
2/3 4/3 19/9 3 ( )
30x+19=2x-9
