计算(a-9/1b^)(3a+3b^)(3a^+37/1b^4)
计算(a-9/1b^)(3a+3b^)(3a^+37/1b^4)
计算:3a+4b/a-b+3b/b-a-4a/a-b
1:计算2(a+b)^2/(a+b)-3(a+b)/(a+b).
计算(a^3-4a^2b-a+4ab^2)/a(a-2b+1)
计算:(b/a)^2÷(a/b)-b^3/a^3(a-b) ÷ 1/a-b
计算a^-2b^-3*(-3a^-1b^2)÷6a^-4b^-2
用简便方法计算 (1)(3a-6b/a+b-(5a-6b/a-b)-(4a-5b/a+b)-(7a-8b/b-a) 第二
4(b-a)(a+b)-(2a-3b)(3a-2b)怎么计算
计算(3a^2+2/1b)(3a^2-2/1b)(9a^4+4/1b^2)
计算(3a^2+1/2b)(3a^2+1/2b)(9a^4-1/4b^2)
计算(3a-2b)(9a*a+6ab+4b*b)-(3a+2b)(9a*a-6ab+4b*b)
计算:(4a^2+9b^2)*(2a+3b)*(2a-3b)
