Have I put the signs in the formula correctly?

Question

Mathematics

Answer 1

Well, ok, the denial of the expression - "not all brave men are worthy of glory" (something I did not immediately enter into the wording).
That is, "there is such a person who is brave and not worthy of glory."

Answer 2

No.

Answer 3

Wrong. The assignment asks you to take the negation of the entire formula. Denial - "not all the brave are worthy of glory", and instead you wrote "only the brave are worthy of glory."
