Answer:
Yo sabré.
Step-by-step explanation:
The verb “sé” is conjugated in the simple present tense for the firt person in singular and comes from the verb “saber.” The future form of this verb is as follows:
(yo) sabré
(tú / vos) sabrás
(él / usted) sabrá
(nosotros) sabremos
(vosotros) sabréis
(ellos / ustedes) sabrán
This tense is used to talk about actions that will take place at a later time. The phrase “Yo sabré” is the equivalent of the English phrase “I will know.”
