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-b

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
