32,6x64+40x32,6-32,6:0,25
=32,6x64+40x32,6-32,6x4
=32,6x(60+40-4)
=32,6x100
=3260
32,6*64+40*32,6-32,6:0,25 ( chia 0.25 là nhân 4 )
32,6 * ( 64 + 40 ) - 32.6 x 4
32,6 * 104 - 130.4
3390.4 - 130.4
3260
ủng hộ mk nha
\(32,6.64+40.32,6-32,6:0,25\)
\(=32,6.64+40.32,6-32,6:\frac{1}{4}\)
\(=32,6.64+40.32,6-32,6.4\)
\(=32,6.\left(64+40-4\right)\)
\(=32,6.100\)
\(=3260\)
Hok tốt
32,6 x 64 + 40 x 32,6 - 32,6:0.25
= 32,6 x 64 + 32,6 x 40 -32,6 x 4
= 32,6 x {64 + 40 -4 }
= 32,6 x 100
=3260
