Tìm x :
X + 35,2 = ( 25,6 + 3,14 ) x 3
x + 35,2 = ( 25,6 + 3,14 ) x 3
x + 35,2 = 28,74 x 3
x = 28,74 x 3 - 35,2
x = 51,02
x + 35,2 = ( 25,6 + 3,14 ) x 3
x + 35,2 = 28,74 x 3
x + 35,2 = 86,22
x = 86,22 -35,2
x = 51,02
x+35,2=28.74*3
x+35.2=86,22
x=86,22-35,2
x=51,02
Vậy x=51,02

a/ 17,5 x 4 x 3 x 25 d/ 7,7 x 9 + 7,7
c/ 4,52 x 12,5 – 2,5 x 4,25 b/ 25,6 x 7,5 + 25,6 x 2,5
a: \(17,5\cdot4\cdot3\cdot25\)
\(=17,5\cdot3\cdot\left(4\cdot25\right)\)
\(=52,5\cdot100=5250\)
b: \(25,6\cdot7,5+25,6\cdot2,5\)
\(=25,6\left(7,5+2,5\right)\)
\(=25,6\cdot10=256\)
c: \(4,52\cdot12,5-2,5\cdot4,25\)
\(=2,5\left(4,52\cdot5-4,25\right)\)
\(=2,5\cdot18,35=45,875\)
