k nha
Học tốt
48.19+48.115+134.54
=48.(19+115)+134.54
=48.134+134.54
=134.(48+54)
=134.102=13668
48.19+48.115+134.54
=48.134+134.54
=134.(48+54)
=134.102
=13668
\(48\cdot19+48\cdot115+134\cdot54\)
\(=48\cdot\left(19+115\right)+134\cdot54\)
\(=48\cdot134+134\cdot54\)
\(=134\cdot\left(48+54\right)=134\cdot102=...\)
bạn tính nốt nhé
48.(19+115) +134.54
48.134 + 134 .54
134.(48+54)
134.102
13668
