Các bạn ơi mình cần gấp lắm ak . Mn trả lời giúp m vs ak . M cảm ơn ak . Thanks mn nhìu . Moa moa
160: {17+[3^3.5-(14+2^7:2^4)]}
\(160:\left\{17+\left[3^3\cdot5-\left(14+2^7:2^4\right)\right]\right\}\)
\(=160:\left\{17+\left[27\cdot5-\left(14+2^3\right)\right]\right\}\)
\(=160:\left\{17+\left[135-\left(14+8\right)\right]\right\}\)
\(=160:\left[17+\left(135-22\right)\right]\)
\(=160:\left(17+113\right)\)
\(=160:130\)
