Here's a breakdown:
* "te gusta" means "you like"
* "lad papas" is not a correct word in Spanish. It seems like a misspelling of "las papas," which means "the potatoes."
Therefore, the corrected phrase would be:
"¿Te gustan las papas?"
This translates to: "Do you like potatoes?"
Note: "Te gustan" is the plural form of "te gusta" because "papas" (potatoes) is plural.
