Đáp án đúng: A
Giải chi tiết:\(\begin{array}{l}A = \left( {1 + 2 + 3 + .... + 100} \right)\left( {{1^2} + {2^2} + {3^2} + .... + {{10}^2}} \right)\left( {65.111 - 13.15.37} \right)\\\,\,\,\,\,\,\,\,\,\,\,\,\,\, = \left( {1 + 2 + 3 + .... + 100} \right)\left( {{1^2} + {2^2} + {3^2} + .... + {{10}^2}} \right)\left( {13.5.3.37 - 13.15.37} \right)\\\,\,\,\,\,\,\,\,\,\,\,\,\,\, = \left( {1 + 2 + 3 + .... + 100} \right)\left( {{1^2} + {2^2} + {3^2} + .... + {{10}^2}} \right)\left( {13.15.37 - 13.15.37} \right)\\\,\,\,\,\,\,\,\,\,\,\,\,\,\, = \,\left( {1 + 2 + 3 + .... + 100} \right)\left( {{1^2} + {2^2} + {3^2} + .... + {{10}^2}} \right).0\\\,\,\,\,\,\,\,\,\,\,\,\,\,\, = 0.\end{array}\)
Vậy \(A = 0.\)
Chọn A.
