[(-2ab)^2*(0.5a^3b^2c)]^3/[-8a(a^2b)^5
[(-2ab)^2*(0.5a^3b^2c)]^3/[-8a(a^2b)^5
[(-2ab)^2*(0.5a^3b^2c)]^3/[-8a(a^2b)^5
[(-2ab)^2*(0.5a^3b^2c)]^3/[-8a(a^2b)^5]
=[4a^2b^2*0.5a^3b^2c]^3/[-8a*a^(2*5)*b^5]
=[(4*0.5)*a^(2+3)*b^(2+2)c]/[-8*a^(1+10)*b^5]
=[2*a^5b^4c]^3/[-8*a^11*b^5]
=[2^3*a^(5*3)*b^(4*3)*c^3]/[-8*a^11*b^5]
=[8*a^15*b^12*c^3]/[-8*a^11*b^5]
=(8÷-8)*a^(15-11)*b^(12-5)*c^3
=-a^4b^7c^3
看错了
[(-2ab)^2*(0.5a^3b^2c)]^3/[-8a(a^2b)^5
=[4a²b²*0.5a³b²c]³/(-8)a^11b^5
=[2a^5b^4c]³/(-8)a^11b^5
=8a^15b^12c^3/(-8)a^11b^5
=-a^4b^7c^3
(ab(a^-2ab)-a^2b(a-3b))÷(3a^b)
3(-ab+2a)-(3a-b)+3ab
(a-b)^3+2ab(a-b)
3ab(a²b-ab²-ab)-ab²(2a²-3ab+2a)
3ab(a²b-ab²-ab)-ab²(2a²-3ab+2a)
(a-b)^2/ab-(a^2-b^2)/ab
ab-(2ab-3a^2b)怎么算?
a-b=3ab,则代数式2a-2b-ab/a-b+2ab的值是()
a-b=3ab,则代数式2a-2b-ab/a-b+2ab的值是()
a+b=5 ab=-3 (2a-3b-2ab)-(a-4b-ab)
已知ab/(a+b)=3,求(3a+ab+3b)/(2a-ab+2b)的值
ab/a+b=3 a-2ab+b/2a-3ab+2b?
已知a+b=A,ab=A+2008,1-2(a+ab)+(ab-2b)=3A.求a+b和ab的值
-2ab(3a^2-2ab-4b^2) (2b-a)b-(2a-b)a-2ab(3a^2-2ab-4b^2)(2b-a)b-(2a-b)a
因式分解a(a+b)-(3ab-b^2)
a-b=5 ab=--1求(2a+3b-2ab)-(a+4b+ab)-(3ab-2a+2b)的值
a^2-3ab+b^2/ab=( )/ab-3
a^2-3ab+b^2/ab=( )/ab -3
