3,5 x 8 x 3 x 1,25
= ( 1,25 x 8 ) x ( 3 x 3,5 )
= 10 x ( 3 x 3,5 )
= 10 x 10,5
= 105
nha bn
\(3,5\times8\times3\times1,25\)
\(=\left(8\times1,25\right)\times\left(3,5\times3\right)\)
\(=10\times10,5\)
\(=105\)
3,5x8x3x1,25
=[3,5x8]x3x1,25
=28x3x1,25
=84x1,25
=105
chúc bạn học giỏi hơn
tk mình nha
3,5x8x3x1,25
=(8x1,25)*(3,5x3)
=10*10,5
=105
k nhé
3,5*8*3*1,25
=3,5*3*(8*1,25)
=3,5*3*10
=3*3,5*10
=3*35
=105
=
3.5 x 8 x 3 x 1.25
= ( 3.5 x 3 ) x ( 8 x 1.25 )
= 10.5 x 10
= 105
3,5 x 8 x 3 x 1,25
= (3,5 x 3) x (8 x 1,25)
= 10,5 x 10
= 105
3,5x8x3x1,25
=(1,25x8)x(3x3,5)
=10x(3x3,5)
=10x10,5
=105
3,5x8x3x1,25
=(3,5x3)x(8x1,25)
=10,5x10
=105
