(a^4/3-8a^1/3b)/(4b^2/3+2√ab+a^2/3)/(1-2*√a/b)*√a其中√是立方根!(a^4/3-8a^1/3b)/(4b^2/3+2√ab+a^2/3)/(1-2*√a
(a^4/3-8a^1/3b)/(4b^2/3+2√ab+a^2/3)/(1-2*√a/b)*√a其中√是立方根!
(a^4/3-8a^1/3b)/(4b^2/3+2√ab+a^2/3)/(1-2*√a/b)*√a
其中√是立方根!
(a^4/3-8a^1/3b)/(4b^2/3+2√ab+a^2/3)/(1-2*√a/b)*√a其中√是立方根!
原式={[a^1/3(a-8b)]/(4b^2/3+2a^1/3b^1/3+a^2/3)}/[(a^1/3-2b^1/3)/(a^1/3)]*a^1/3
=a^1/3*a^1/3*a^1/3
=a
上面是我的QQ空间,在相册里有个叫题的图片,那个就是这道题的答案了
题目看不懂
(a^4/3-8a^1/3b)../..(4b^2/3+2√ab+a^2/3)../..(1-2*√a/b)*√a
看不出哪是分子,哪是分母
1/(a-b)-1/(a+b)-(2b)/(a^2+b^2)-(4b^3)/(a^4+b^4)+(8b^7)/(b^8-a^8)快
1/a-b-1/a+b-2b/a^2+b^2-4b^3/a^4+b^4+8b^7/b^2-a^2
(3a-6b)/(a+b) - (5a-6b)/(a-b) - (4a-5b)/(a+b) - (7a-8b)/(a-b) 快
(3a-6b/a+b)-(5a-6b/a-b)-(4a-5b/a+b)-(7a-8b/b-a)
计算:(4a-b)^2-[8a*(a-b)-(3a-b)*(3a+b)]

[3(a+b)^4-1/2(a+b)-a-b]/(a+b)
1/4(a-b)^2+3(a-b)(a+b)+9(a+b)^2
计算:3a+4b/a-b+3b/b-a-4a/a-b
2(a+b)-[4(a+b)-3(a+b)]一[5(a-b)+(a-b)]过程
化简【3A方-(A+B)(B-A)】【4(-B-A)(B-A)+5B方】
计算(a/a-b+b/b-a)/(1/a+b)的结果 (1)a-b (2)ab (3)a^2-b^2 (4)a+b
已知A=-1/2a^2b,B=4ab^3-8a^2b^2,试用a,b表示整式2A^2B(A-B)+A^2B(2B-A)
(3a+4b)(7a-8b)+(11a+2b)(8a-7a)
等式:(a+b)^0=1 (a+b)^1=a+b (a+b)^2(a+b)^0=1(a+b)^1=a+b(a+b)^2=a^2+2ab+b^2(a+b)^3=a^3+3a^2b+3ab^2+b^3问:(a+b)^4=?(a+b)^5=?``````` (a+b)^9=?
