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

Yes

The word "exóticas" is identical in spelling, meaning, and grammatical function in both Brazilian and European Portuguese. The only difference lies in pronunciation. Brazilian Portuguese tends to have more open vowels and a "syllable-timed" rhythm, which gives the word a more melodic, flowing sound. In contrast, European Portuguese features more closed or reduced vowels and a "stress-timed" rhythm, making the pronunciation sound more "clipped" or compressed.
