a2·a3+(-a2)3-2a(a2)3-2［(a3)3÷a3］；
a^2*a^3+(-a^2)^3-2a(a^2)^3-2[(a^30^3/a^3]
(3a^2)^3-6a^3(2a^3+3a^2+a)
1.( -2/2a+3) + (3/3-2a)+[ 2a+15/ (2a-3)(2a+3)]
(-2a)^5-(-3a^2)^3-(-2a^3)^2+(4a^3)*(-a)^2
(2a+3b)^2-(3a-2b)^2 =(2a+3b+3a-2b)(2a+3b-3a+2b) =
（a^2)^3-(-3a^3)^2+a乘a^2乘a^3
计算 2(a^3)^2*a^3+(3a^3)^3-(5a)^2*a^7
A=[a1,a2,a3] B=[3a1-2a2 ,3a2-2a3 ,2a3-a1-2a2] ｜B｜=28 求｜A｜
(a^2-3-3)^2-a(a^2-3)-2a^2因式分解
