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

Yes

The word "resultado" is identical in both Brazilian and Continental Portuguese in terms of meaning, spelling, and grammar. The only difference lies in pronunciation. In Brazilian Portuguese, vowels are generally more open and clearly articulated. In Continental Portuguese, unstressed vowels tend to undergo "vowel reduction," meaning they are shortened or "swallowed," which makes the word sound more clipped to a Brazilian ear.
