How can I say "I don't know how to answer that question." in french?

I wrote:
Je ne sais pas comment reponds a cet question.

I don't feel like that is correct, can someone help me?

Je ne sais pas répondre à cette question

to correct the accent marks:

répondre à cette question-là. Since cette could be this or that, you can tack on the suffix to clarify it.

Sra (aka Mme)

Je ne sais pas comment repondre a cette question.

Your attempt is very close, but there are a couple of mistakes. To say "I don't know how to answer that question" in French, you can say: "Je ne sais pas comment répondre à cette question." Here's how to break down the sentence:

1. "Je" means "I" in English.
2. "Ne sais pas" means "do not know" in English. It is the negative form of the verb "savoir," which means "to know."
3. "Comment" means "how" in English.
4. "Répondre" means "to answer" in English. It is the infinitive form of the verb.
5. "À cette question" means "to that question" in English. "À" is a preposition meaning "to," and "cette question" means "that question."

So, putting it all together, you would say "Je ne sais pas comment répondre à cette question" to mean "I don't know how to answer that question" in French.
