Cho \(P = ( - 13) (153 - 45) + 153.( 13 - 45) + 125.( - 2)^3. ( - 1)^{2n} , (n \in N^*)\), chọn câu đúng.

* Hướng dẫn giải

 \(\begin{array}{*{20}{l}} {P = ( - 13.153) + (13.45) + (153.13) - (153.45) + 125.{{\left( { - 2} \right)}^3}.{{\left( { - 1} \right)}^{2n}}{\mkern 1mu} {\mkern 1mu} {\mkern 1mu} }\\ {P = \left[ {(153.13) - (13.153)} \right] + \left[ {(13.45) - (153.45)} \right] + 125.\left( { - 8} \right){\mkern 1mu} .1{\mkern 1mu} {\mkern 1mu} }\\ {P = 0 + 45.(13 - 153) + 125.\left( { - 8} \right)}\\ {P = 45.( - 140) - 1000}\\ {P = - 6300 - 1000}\\ {P = - 7300{\mkern 1mu} {\mkern 1mu} {\mkern 1mu} } \end{array}\)
