Final answer:
The appropriate verb to fill in the blank is 'limpiamos' because 'Tú y yo' is the subject.
Step-by-step explanation:
The appropriate verb to fill in the blank in the sentence 'Tú y yo ______ el baño' is limpiamos.
This is because 'Tú y yo' translates to 'You and I' in English, which is the subject of the sentence. In Spanish, when the subject is 'Tú y yo', the verb that follows should be in the first person plural form, which is 'limpiamos'.
For example: 'Tú y yo limpiamos el baño juntos todos los sábados' means 'You and I clean the bathroom together every Saturday'.
