cac ban giai nhanh giup minh nha! ai nhanh minh k!
Tính giá trị của các biểu thức sau:
a) A = (2,1-1,965) : (1,2.0,045)/0,00325:0,013 - 1:0,25/1,6.0,625
b) [ (2,4+1/5/4).4,375/(2/3-1/6) - (2,75-1/5/6).21/8/20-0,45] : 67/200
c) (1+1/1.3).(1+1/2.4).(1+3.5)...(1+1/99.101)
d) 47.28.(-2)-5/3.215.162-5.22.10242
a) -11/12 x X+ 0,25=5
b) (x-1)5=-32
-11/12.x+0,25=5/6
-11/12 x X + 0,25 = 5/6
1) 3y/5=21/10
2) -11/12.y+0,25=6/5
3) 5x/4=-3/2
4) 8:(1/4.x)=2 : 0,02
