[(2ab)^4 /(8a^2b^3)]^3/[-(1/2)a^2b)^3求过程!
[(2ab)^4 /(8a^2b^3)]^3/[-(1/2)a^2b]^3
=(16a^4b^4/8a^2b^3)^3/(-1/8a^6b^3)
=(2a^2b)^3/(-1/8a^6b^3)
=8a^6b^3/(-1/8a^6b^3)
=-64
原式=[(16a^4b^4/(8a^2b^3)^3]/(-1/2a^2b)^3
=(2a^2b)^3/(-1/2a^2b)^3
=[2a^2b/(-1/2a^2b)]^3
=(-4)^3
=-64
a^2b-ab+2ab^2-5a^b-4ab+3ab^2化简快
(2a-5b+3ab)+(3a-b)-(8a-9b+ab),其中a-b=4,ab=3
先化简,再求值.(2a-5b+3ab)+(3a-b)-(8a-9b+ab),其中a-b=4,ab=3.
1.(a-b)(a^2+ab+b^3)2.(a-b)(a^3+a^2b+ab^2+b^3)3.(a-b)(a^4+a^3b+a^2b^2+ab^3+b^4)4.(a-b)(a^10+a^9b+a^8b^2+...+ab^9+b^10)5.(X-1)(x^5+x^4+x^3+x^2+1)6.(a-b)(a^n+a^n-1b+a^n-2b^2+...+ab^n-1+b^n)
5ab^2-{2a^b-[3ab^2-(4ab^2-2a^2b)]}
1/4a^2b^2{3ab(a+b)-5a(ab-b^2)}=?
(2a*2b*3-8a*4b)/(2a*2b-ab*2)
约分:3ab+3b^2/a^2b+2ab^2+b^3.分式约分还有一个:8ab+16a/b^2+4b+4
(a-b)^3+2ab(a-b)
(2a-5b+3ab)+(3a-b)-(8a-9bz+ab),其中a-b=4,ab=4
8ab-{4a-3[6ab+5(ab+a-b)-7a]-2}这道题怎么做
已知A=3A^2B+3AB^2+B^4,B=-8AB^2+2A^2B+C^4,求A-2B
因式分解:2a^2b-4ab^2+8ab
-3/4ab+2/3a^2b+ab-a^2b-1/2ab-5/3a^2b
因式分解:2a^b-4ab^2+8ab
证明(a^2+ab+b^2)^2+4ab(a+b)^2=(a^2+3ab+b^2)
证明(a^2+ab+b^2)^2+4ab(a+b)^2=(a^2+3ab+b^2)
a+b=4,ab=-2,求代数式(4a-3b-2ab)-(a-6b+ab)
