Question

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?

Answer 1

Je ne sais pas répondre à cette question

Answer 2

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)

Answer 3

Je ne sais pas comment repondre a cette question.
