2.125.18+36.252+4.223.9 = 21600
Chúc bạn học giỏi nhé !
\(=36\times125+36\times252+36\)\(\times223\)
\(=36\times\left(125+252+223\right)\)
\(=36\times600\)
\(=21600\)
2 x 125 x 18 + 36 x 252 + 4 x 223 x 9
= (2 x 18) x 125 + 36 x 252 + (4 x 9) x 223
= 36 x 125 + 36 x 252 + 36 x 223
= 36 x (125 + 252 + 223)
= 36 x 600
= 21600
2x 125x 18+ 36x 252+ 4x 223x 9.
=( 2x 18)x 125+ 36x 252+( 4x 9)x 223.
= 36x 125+ 36x 252+ 36x 223.
= 36( 125+ 252+ 223).
= 36. 600.
= 21600.
