There are many kinds of questions about Algebra in the exam paper. This paper selects several types of examinations for algebraic patterns in the mathematics questions in the recent two years. For students only review reference. First, review the power of the algorithm Example 1 (2005 Jiangxi Province) the following operations are correct () (A) a6 a3 = a18 (B) (-a) 6 (-a) 3 = -a9 (C) A6÷a3=a2 (D)(-a)6(-a)3=a9
