(a+2b)(2a+4b)(3a+6b)(4a+8b)
[8(a+b)^6+4(a+b)^4+(-a-b)^3]÷[2(a+b)＾3].
(3a-6b)/(a+b) - (5a-6b)/(a-b) - (4a-5b)/(a+b) - (7a-8b)/(a-b
(3a-6b/a+b）-(5a-6b/a-b)-(4a-5b/a+b)-(7a-8b/b-a)
1.（a-b)^2（b-a)^3(a-b)^-4
如果a-2b/a+2b=3,求a+2b/a-2b+3a-6b/4a+8b
（a-2b)/(a+2b)=3,求(a+2b)/(a-2b)+(3a-6b)/(4a+8b)的解,
3a^2b-{2a^2b+[9a^b-(6a^2b+4a^2)]-(3a^2b-8a^2)}=
计算：3a+4b/a-b+3b/b-a-4a/a-b
3a/a-4b +a+b/4b-a -7b/a-4b
a-2b/a+2b=3,求2+2b/a-2b+3a-6b/4a+8b的值
计算a^-2b^-3*(-3a^-1b^2)÷6a^-4b^-2
