Question

Combine the radicals .

6


–6

Answer 1

I’m not sure how the radicals were meant to be written — the symbols didn’t come through. Could you retype the expression using sqrt(...) or root notation? For example write sqrt(6) or cbrt(6).

Possible interpretations and results:

- If you meant √6 − √6 (or √6 and −√6): they combine to 0.
- If you meant √6 − 6: that simplifies no further (it’s √6 − 6).
- If you meant √6 + √(−6): √(−6)=i√6, so √6 + √(−6) = (1 + i)√6.
- If you meant cube roots ∛6 − ∛6: that equals 0.

Tell me which one you mean (or paste the original with radical symbols) and I’ll combine them.
