Is the word raquetes the same in Brazilian and European Portuguese?

Yes

The word "raquetes" is spelled and defined identically in both Brazilian and Continental Portuguese. The only difference is the pronunciation (phonology). In Brazil, the unstressed vowels are more open, and the final "e" is typically pronounced as an /i/ sound (ra-KE-chis). In Portugal, unstressed vowels are much more closed and often reduced or almost silent (ra-KE-tɨʃ).

Brazilian Portuguese Examples:

1. Eu comprei raquetes novas para jogar tênis. (I bought new rackets to play tennis.)
2. Essas raquetes de beach tennis são muito legais! (Those beach tennis rackets are really cool!)
3. Você viu onde eu deixei as raquetes? (Did you see where I left the rackets?)
4. Preciso trocar as cordas das minhas raquetes. (I need to change the strings on my rackets.)
5. As raquetes de squash são bem diferentes das de tênis. (Squash rackets are quite different from tennis ones.)

Continental Portuguese Examples:

1. Eu comprei raquetes novas para jogar ténis. (I bought new rackets to play tennis.)
2. Estas raquetes de padel são muito fixes! (These padel rackets are very cool!)
3. Tu viste onde eu deixei as raquetes? (Did you see where I left the rackets?)
