"The women are beautiful."
예쁘다 - not conjugated. informal if you use it in speech // 예쁩니다 - formal and polite // 예뻐요 - still polite but kind of informal // 예뻐 - informal. used with friends and people close to you around your age or younger, people in your same social status or lower. using it with older people / people above you without permission may result in an angry fit lol
same for these (and any other verb/adjective): 아름답다 // 아름답습니다 // 아름다워요 // 아름다워
