They have pretty much the same meaning I would say we use have to more frequently. I think that people use must when they are implying that if you don’t they’ll be consequences. For example you have to clean your room. You must clean your room or else you will get no dessert.

Hi! Both of those sentences are correct. There is a small difference in meaning. "Must" is a stronger word than "have to".

Hola Ls Ad La respuesta correcta en ambos casos es “have to” “Must” significa que debe hacerlo pero si no lo hace no pasa nada. Por ejemplo, “debo comer menos”, “debo cortarme el pelo” “Have to” significa que tiene que hacerlo, es una regla y si no lo hace hay consecuencias. “Tengo que cargar combustible o mi auto se detendrá”, “tengo que pagar la factura de la luz” Espero sea de ayuda
