The full score is 150, and the test time is 120 minutes. The first Ⅰ (multiple choice questions (5 points, 60 points) A total of 60 points) 1. In the cube ABCD - A 1, B 1, C 1, D 1, the edge of the diagonal-line AC 1 is (a.12 b. 6 c. 4 d. 2). ) The largest of the binomial coefficients in the expansion of (a + b) 2 n + 1 (n) n *) is ( B. a. n item n + 1 item c. d. n + 2 item n + 1 or n + 2 item 3, straight line m, n equals the Angle of plane by alpha into is m ∥ n () a. b. need not sufficient condition necessary and sufficient condition c. and d. neither nor necessary and sufficient condition 4, A 2 3 + A + A + A 5 + 2...
