Conjugating Formal Mandates in Spanish
Out of my spanish homework I can't seem to get the answers for three questions. The part in bold is what is incorrect.
An angry citizen sends a letter to the local newspaper directed several people. Fill your requests using the formal mandates of the verbs in brackets. Follow the example.
Al alcalde: "Sea más generoso." (ser más generoso)
A la dueña de la discoteca: "no hazan tanto ruido." (no hacer tanto ruido)
A los ciudadanos: " indican el camino a los turistas ." (indicar el camino a los turistas)
A toda la gente de la ciudad: " relajase ." (relajarse)

Generally speaking, to get your formal commands- Usted and Ustedes, the first thing to do is get the "Yo" form of the present indicative. This is no problem with regular verbs, like "Trabajo" "como" "escribo" You merely remove the "o" ending and replace it with the appropriate "opposite" ending of what you would expect.
Trabjajo gives us "trabaje" and"trabajen". Como gives us "coma and coman" escribo gives us "escriba" and "escriban"
The irregular verbs present more of a challenge, but the principle is the same. Here are a few sample irregular verbs.
Salir--Yo form = salgo, the mandatos are salga and salgan
Hacer. Yo form = hago, the mandatos are haga and hagan.
Ver. Yo form = veo. the mandatos are vea and vean.
Also when dealing with the stem-changing verbs, just remember, whatever the present tense "yo" form is, just drop the "o" and add that "opposite" ending. "e"and "en" for "ar" verbs and "a" and an" for "er" and "Ir" verbs.
Special cases are "ser", "estar" and "ir" these become. "sea/n, esté/n and vaya/n"
And I think that that's the whole enchilada. 
Except for those few that have a spelling change like "indeque/n" These come up with verbs like "indicar" "buscar" "llegar" "pagar, and other verbs ending in "car" "gar" and "zar" where the "c" changes to "qu" the "g" to "gu" and "z" changes to "c"
I hope I haven't given too much here, I tried to make it as simple as possible, but it is not a simple matter.
I will try and edit this answer later with the links on this site to imperatives and conjugations. Effectively on the ones you are using they are all affirmative 3rd person plural/singular and so they are the same as the present subjunctive. Often teachers get students to study the imperative before learning the subjunctive mood as you are part way there. The first one in bold should be 3rd person singular = haga - it is similar to decir which is 'diga' which they use in Spain when answering the phone. The next one has a different spelling to make the sound = indiquen
The third one: relajese
AR verbs in the subjunctive 3rd person end in e eg habla becomes hable
NB the imperative for tu and vosotros is not the present subjunctive where the command is affirmative but is present subjunctive if it is negative.
He or she is asking about the Imperative...
