What is the proper form?
Nosotros (deber/estudiar)___ mucho esta semana.
debemos/estudiamos or debemos/estudiar
"debemos estudiar" is the correct form.
The conjugated verb "debemos" (we must; we have to) takes the infinitive "estudiar" (to study)
Note that to study is the infinitive = estudiar. If you write two conjugated verbs together, such as "debemos estudiamos" you have "we ought to/we must we study/do study/are studying. (a run-on sentence)
