\(272:16-5+4\left(30-6-255:17\right)\)
\(=17-5+4.9\)
\(=12+36\)
\(=48\)
\(25.8-12.5+272:17-8\)
\(=200-60+16-8\)
\(=140+16-8\)
\(=148\)
= 17 - 5 + 4.9
= 12 + 36
= 48
2. 25 . 8 - 12.5 + 272 : 17 - 8
= 200 - 60 + 16 - 8
= 140 + 16 - 8
= 148
dễ mà bạn
272:16-5+4(30-6-255:17)
= 272:16-5+4(30-6-15)
= 272:16-5+4(24-15)
= 272:16-5+4.9
= 17-5+36
= 12+36=48
25.8-12.5+272:17-8
= 200-60+16-8
= 140+16-8
= 156-8
= 148
bạn kia làm đúng rồi
chúc ban học tốt
