\(100:25.5-3.121:\left[3.\left(364-360\right)\right]\)
\(=20-363:\left(3.4\right)\)
\(=20-363:12\)
\(=20-30,25\)
\(=-10,25\)
Mk thấy đề của bn cứ sai sai thì phải......
100 : 25 * 5 - 3 * 121 : [3 * (364 - 360)]
= 4 * 5 - 363 : [3 * 4]
= 20 - 363 : 12
= 20 - 30,25
= -10,25
~Study well~

\(100:25.5-3.121:\left[3.\left(364-360\right)\right]\)
\(=20-363:\left(3.4\right)\)
\(=20-363:12\)
\(=20-30,25\)
\(=-10,25\)
\(100:25\cdot5-3\cdot121:\left[3\cdot\left(364-360\right)\right]\)
\(=100:25\cdot5-3\cdot121:\left[3.4\right]\)
\(=100:25\cdot5-3\cdot121:12\)
\(=4\cdot5-363:12\)
\(=20-30,25\)
\(=-10,25\)
Dấu chấm là dấu nhân.
\(100:25\times5-3\times121:\left[3\times\left(364-360\right)\right]\)
\(=4\times5-3\times121:\left[3\times4\right]\)
\(=4\times5-3\times121:12\)
\(=20-363:12\)
\(=20-30,25\)
\(=-10,25\)
