các anh chị fiair giúp em với ạ

Answer 1

giải em viết nhầm ah

Answer 2

\(280000-\left\{3^6.\left[370-\left(2^4:2^2.13\right)\right]\right\}\)

\(=280000-\left\{729.\left[370-\left(16:4.13\right)\right]\right\}\)

\(=280000-\left\{729.\left[370-52\right]\right\}\)

\(=280000-\left\{729.318\right\}\)

\(=280000-231822\)

\(=48178\)

Answer 3

\(280000-\left\{3^6..\left[370-\left(2^4:2^2.13\right)\right]\right\}\)

\(=280000-\left\{3^6\left[370-\left(16:4.13\right)\right]\right\}\)

\(=280000-\left\{3^6\left[370-52\right]\right\}\)

\(=280000-\left\{729-318\right\}\)

\(=280000-411\)

\(=279589\)

chỗ có 2 dấu . coi là 1 và dấu . là dấu nhân

Answer 4

\(280000-\left\{3^6.\left[370-\left(2^4.2^2.13\right)\right]\right\}\)

\(=280000-\left\{729.\left[370-52\right]\right\}\)

\(=280000-\left\{729-318\right\}\)

\(=280000-231822\)

\(=48178\)
