计算:(a-1/6b)(2a+1/3b)(3a²+1/12b²)
计算:(a-1/6b)(2a+1/3b)(3a²+1/12b²)
1:计算2(a+b)^2/(a+b)-3(a+b)/(a+b).
化简 (a+b)²+2a(a-1/2b)-3(a-b)(a+b)
计算:(b/a)^2÷(a/b)-b^3/a^3(a-b) ÷ 1/a-b
计算:a/b(a-b)-b/a(a-b);(1/a+1/b)÷a²+2ab+b²/a+b.
计算a^-2b^-3*(-3a^-1b^2)÷6a^-4b^-2
请化简以下两道题(a+2b)(a-2b)-1/2b(a-8b)(a+b)²+(a-b)(2a+b)-3a
计算(a-b分之1-a²-b²分之b)÷a+b分之a
计算代数式a-b+(a-2b)(a-b)+(a-2b)(a-b)²+(a-2b)(a-b)^3 当a=-3
计算:(1)(3a+2b)(-3a-2b)(2)(0.5a+3分之1b)²
计算(a^3-4a^2b-a+4ab^2)/a(a-2b+1)
2a(a-2b)-1/2b(3a+b)计算
