5a-2/3b+4a-1/3b化简5a-2/3b+4a-1/3b化简5a-2/3b+4a-1/3b化简=(5a-2+4a-1)/3b=(9a-3)/3b=(3a-1)/b原式=9a-b
5a-2/3b+4a-1/3b化简
5a-2/3b+4a-1/3b化简
5a-2/3b+4a-1/3b化简
=(5a-2+4a-1)/3b
=(9a-3)/3b
=(3a-1)/b
原式=9a-b
化简【3A方-(A+B)(B-A)】【4(-B-A)(B-A)+5B方】
2(a+b)-[4(a+b)-3(a+b)]一[5(a-b)+(a-b)]过程
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=?
5(a*a*b-3*a*a*b)-2*(a*a*b-7*a*b*b)
化简 (a+b)²+2a(a-1/2b)-3(a-b)(a+b)
[(4a+3b)(4a-3b)-(3a=3b)(2a-3b)]/5a 化简
a+a-a+2a-3a-2b+3b-5b+3b-4b-5b
已知A=3A-4B+C,B=5A+4B+2C,求[1]A-B;[2]A+B;[3]2A-3B.
化简:[2/3a - 2/(a+b) * (a+b/3a - a - b)] / (a-b)/a
(3a^2*b-7a*b^2-a^2*b^2)*5a*b化简
a^2+5(a-b)(a+b)-(3a-2b)^2+9b^2,化简
化简:7(a-b-c)-5(a+b-c)+3(a-b-c)+(a+b-2)
a^2+b(b+1)a+b^3 ,化简
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)
(a-b)(a^5+a^4b+a^3b^2+ab^4+b^5)bggg
[(a+b)^-3(a-b)^5/(a-b)^-2(a+b)^4]^2怎么写
5(a-b)-4(a+b)-3(a-b)+2(a+b)怎么算?
(a-b)^2*(b-a)^5+(b-a)^3*(a-b)^4=?
