\(0,5\times2,5\times40\times200\)
\(=\left(0,5\times200\right)\times\left(2,5\times40\right)\)
\(=100\times100\)
\(=10000\)
Học tốt
=(2,5*40)*(0,5*200)
=100*100
=10000
(0,5×200)×(2,5×40)
100×100
10000
đúng thì tích
0.5 x 2.5 x 40 x 200
= ( 2.5x40 ) x ( 200x0.5 )
= 100 x 100
= 1000
=( 2,5*40)*(0,5*200)
=100*100
=10000
