计算(a-9/1b^)(3a+3b^)(3a^+37/1b^4)
计算(a-9/1b^)(3a+3b^)(3a^+37/1b^4)
计算(a-9/1b^)(3a+3b^)(3a^+37/1b^4)
(a-b²/9)(3a+3b²)(3a²+b⁴/37)
=(3a²+3ab²-ab²/3-b⁴/3)(3a²+b⁴/37)
=(3a²+8ab²/3-b⁴/3)(3a²+b⁴/37)
=9a⁴+3a²b⁴/37+8a³b²+8ab⁶/111-a²b⁴-b⁸/111
=9a⁴-34a²b⁴/37+8a³b²+8ab⁶/111-b⁸/111
计算(a-9/1b^)(3a+3b^)(3a^+37/1b^4)
(3a+b)(b-3a)计算
计算:(a+b)(2a-3b)
计算(a-b)(b-a)^3+[(a-b)^2]^2
计算a/a+2b-b/3a-b
计算(5a-3b)^2+(a+b)(a-b)
计算:(b/a)^2÷(a/b)-b^3/a^3(a-b) ÷ 1/a-b
计算:3a+4b/a-b+3b/b-a-4a/a-b
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
(b-a)^3怎么计算?
计算(a^3-4a^2b-a+4ab^2)/a(a-2b+1)
计算:(4a-b)^2-[8a*(a-b)-(3a-b)*(3a+b)]
计算a+[a+b]+[a+2b]+[a+3b]+...+[a+99b]
计算:a+(a+b)+(a+2b)+(a+3b)+……+(a+99b)
计算a+(a-b)+(a-2b)+(a-3b)+.+(a+99b)
计算:[3a²/(a+b)](a²-b²)÷[(b-a)/(a+b)]²
计算3(a+b)-2(a-b)-a=
计算:(4a^2+9b^2)*(2a+3b)*(2a-3b)
