Given:

U be the set of all books, N the set of all novels, and H be the set of all hardcover books.

To find:

The description for the sets
N\cap H and
H' in words.

Solution:

We have,

U = The set of all books

N = The set of all novels

H = The set of all hardcover books.

We know that
N\cap H means common elements of set N and set H.

Therefore,
N\cap H is set of all books that are both novels and hardcover books.

We know that
H' is the set of elements of universal set except the elements of set H.

Therefore,
H' is the set of all books that are not hardcover books.
