Write forms of tener que to tell what the following people have to do.

Yo presentarte a mis amigos.

¡Ellos conocerte!

Can someone help me with the first 2 to get started?

My Spanish is rusty, but you don't want an infinitive.

If in the future,

Yo te presentaré a mis amigos.

If in the present,

Yo te presento a mis amigos.

Except for a command, the direct object pronoun comes before the verb.

Don't you want the third person plural to match the verb to the subject?

¡Ellos conocerten!

To express what someone has to do using the verb "tener que" (have to), you need to conjugate the verb "tener" according to the subject pronoun you're using and follow it with the preposition "que" and the infinitive form of the verb that represents the action.

For the first sentence:
- "Yo" is the subject. The verb "tener" needs to be conjugated into the first-person singular form, which is "tengo".
- The action of the sentence is "presentarte a mis amigos", which means "to introduce you to my friends". The infinitive form of this action is "presentar".

Putting it all together, you get:

Yo tengo que presentarte a mis amigos. (I have to introduce you to my friends.)

Now, let's move on to the second sentence:

- "Ellos" is the subject. The verb "tener" needs to be conjugated into the third-person plural form, which is "tienen".
- The action of the sentence is "conocerte", which means "to meet you". The infinitive form of this action is "conocer".

Putting it all together, you get:

¡Ellos tienen que conocerte! (They have to meet you!)

Hope this helps you get started! Let me know if you have any more questions.
