Vậy biểu thức có gt là : 4

tích cho mk nha

good luck !

Rối não :)) Thề ngu phần số âm cực =))

bn đùa à dấu "^" là dấu gì trong toán học

Các bạn ơi mình cần gấp lắm ak . Mn trả lời giúp m vs ak . M cảm ơn ak . Thanks mn nhìu . Moa moa

\(160:\left\{17+\left[3^3\cdot5-\left(14+2^7:2^4\right)\right]\right\}\)

\(=160:\left\{17+\left[27\cdot5-\left(14+2^3\right)\right]\right\}\)

\(=160:\left\{17+\left[135-\left(14+8\right)\right]\right\}\)

\(=160:\left[17+\left(135-22\right)\right]\)

\(=160:\left(17+113\right)\)

\(=160:130\)

\(=\dfrac{16}{13}\)
