[(-3ab)^2a^3-2a^2(3ab^2))^3*1/2b]÷(-3ab^2))^2
[(-3ab)^2a^3-2a^2(3ab^2))^3*1/2b]÷(-3ab^2))^2
[(-3ab)^2a^3-2a^2(3ab^2))^3*1/2b]÷(-3ab^2))^2
[(-3ab)^2a^3-2a^2(3ab^2))^3*1/2b]÷(-3ab^2))^2
=(9a^2b^2*a^3-2a^2*27a^3b^6*b/2)/(9a^2b^4)
=(9a^5b^2-27a^5b^7)/(9a^2b^4)
=(a^3-3a^3b^5)/(b^2).
[(-3ab)^2a^3-2a^2(3ab^2))^3*1/2b]÷(-3ab^2))^2
=(9a^2b^2a^3-2a^2*27a^3b^6*1/2b]÷(9a^2b^4)
=(9a^5b^2-27a^5b^7)÷(9a^2b^4)
=(9a^5b^2)÷(9a^2b^4)-(-27a^5b^7)÷(9a^2b^4)
=a^3/b^2+3a^3b^3
3(-ab+2a)-(3a-b)
3(-ab+2a)-(3a-b)
(a-b)^3+2ab(a-b)
a^3-ab^2 =a （a^2 -b^2) =a(a+b)(a-b)
3(-2ab+3a)-(2a-b)+6ab
3(-ab+2a)-(3a-b)+2ab
-3ab-4a^2+3a^2+5ab
3（-ab+2a)-(3a-b）+3ab
化简：（3a^2+2ab)-2(a+ab)
(2a²-ab+1)-2(a-2ab+3)
化简:(-2ab+3a)-(2a-b)+6ab
因式分解 a^3+2a^2b+ab^2-a
计算：5ab-a²-2(ab-3a)²
(3a-ab+7)-(-4a+2ab+7)
-2ab乘以(-a^+6a^b-3a+b)
18ab(a-b)^2-12a(b-a)^3
因式分解:a^3-ab^2
计算：a^2×(-a)^2×(-a)^3（-ab）^2·（2a^2-ab-1)
