\(0,5\times40\times0,2\times20\times0,25\)
\(=\left(0,5\times0,2\right)\times\left(40\times20\times0,25\right)\)
\(=0,1\times200\)
\(=20\)

140 - 0,5 x 40 x 5 x 0,2 x 20 x 0,25 - 40
= (140 - 40 ) - (0,5x20) x (40 x 0,25)
= 100 - 100
= 0
140 - 0,5 x 40 x 5 x 0,2 x 20 x 0,25 - 40
= (140 - 40 ) - (0,5x20) x (40 x 0,25)
= 100 - 100

X : 0,125 + X : 0,5 + X x 10 = 40
x : ( 0,125 + 0,5 + 10 ) = 40

x = 40 x 10,625

#)Giải :
X x 3 + X : 0,5 = 40
X x 3 + X x 2 = 40
X x ( 3 + 2 ) = 40
X x 5 = 40
X = 40 : 5
X = 8
#~Will~be~Pens~#
X x 3 + X : 0.5 = 40
X x 3 + X x 2 = 40
X x ( 3 + 2 ) = 40
X x 5 = 40
X = 40 : 5
X = 8
Xx3+X :0,5=40
Xx3+Xx2 =40
Xx(3+2) =40
Xx5 =40
X =40:5
X =8
:0,5=x2 bạn nhé
X x 3 + X : 0,5 = 40
X x 3 + X x 2=40
X x (3+2) = 40
X x 5 = 40
X = 40 : 5
X =8
nhớ cho mik nhé
