整式的定义：单项式和多项式统称为整式.但2+2/x既不是单项式 也不是多项式 故它不是整式.

是分式，化简后也是

2/n 是整式还是分式 2x²/x 是整式还是分式 2x/3x是分式还是整式? 2x/x 分式还是整式如说是整式 则 化简后得X如说是分式 则 分母含有X到底是整式还是分式? 1/2 x的平方是整式还是分式 2分之1(x+y)是分式还是整式 （x-2）/3是整式还是分式 m^2/m是分式还是整式 2x^2/x是分式还是整式?老师貌似说是分式诶. (2a^2)/a是整式还是分式还是都不是整式分式?请解析! X-2分之X的平方-4是分式还是整式? 过程啊,谢谢 x/3=(x-1)/2是整式方程还是分式方程 （2a^2)/a 是整式还是分式? （2a^2)/a 是整式还是分式? 4a²+a分之2是整式还是分式? a^2/a是整式还是分式,请说明理由 2+2/x是分式吗,还是个整式,2+2/x是分式吗,还是个整式?是不是能化简成A/B类得都是分式?化简后的也算吗、?..顺便问下英语He was doing laundry at home ( )in time?on time?at times?all the time? 2/x∧2+y∧2+2是分式还是整式 π/2 是有理式,无理式,整式,分式?
