=48x72+72x18+(8x9)x34
=48x72+72x18+72x34
=72x(48+18+34)
=72x100
=7200
48 x 72 + 72 x 18 + 8 x 9 x 34
= 48 x 72 + 18 x 72 + 34 x 72
= ( 48 + 18 + 34 ) x 72
= 100 x 72
= 7200
48x72 + 72x18 + 8x9x34
= 48 x 72 +18x72 +x 72x34
= 72 x( 48+18+34)
= 72 x 100
= 7200
Theo bài ra , ta có:
72 x 48 + 72 x18 + 8 x 9 x 34
72 x 48 + 72 x 18 + 72 x34
72 x [ 48 + 18 + 34 ]
72 x 100
7200
48 x 72 + 72 x 18 + 8 x 9 x 34
= 48 x 72 + 18 x 72 + 34 x 72
= ( 48 + 18 + 34 ) x 72
= 100 x 72
= 7200
