Answer:
The sentences with the correct form and tense of the verb in subjuctive or the conditional of “haber" is:
- A la profesora le gusta que los alumnos <u>hayan salido</u> a comer a la cafetería.
Explanation:
The translation of the sentence is:
- The teacher likes that the students <u>have gone out</u> to eat at the coffee shop.
Within the sentence two verbs have been used: the first is the verb <em>"haber"</em> in its form in <u>Present subjunctive</u>, which is usually used when before the noun <em>"los estudiantes"</em> is the subordinate conjunction <em>"that"</em> or <em>"que"</em> in Spanish, below I show you the possible conjugation:
- <em>Yo </em><em>haya</em><em>.
</em>
- <em>Tú </em><em>hayas</em><em>.
</em>
- <em>Él </em><em>haya</em><em>.
</em>
- <em>Ella </em><em>haya</em><em>.
</em>
- <em>Ello </em><em>haya</em><em>.
</em>
- <em>Nosotros </em><em>hayamos</em><em>.
</em>
- <em>Ellos </em><u><em>hayan</em></u><em>.
</em>
How the noun <em>"los estudiantes"</em> can be replaced by the personal pronoun <em>"ellos,"</em> the correct conjugation is <u><em>"hayan,"</em></u> after in the sentence was used the verb <em>"salir"</em> in its perfect form. which is characterized by ending in <em>"ado"</em> or <em>"ido"</em> by removing the two letters of the verb infinitive, so, to the verb <em>"salir"</em> you remove the termination <em>"ir"</em> and add <em>"ido"</em> resulting in the word <u><em>"salido."</em></u>
