Why is a general rule sought instead of Pascal's triangle?
ALarger powers get held
BLarger powers get harder
CLarger powers get halved
DLarger powers get hidden
Answer & Solution
Correct answer: B. Larger powers get harder
1. Every earlier row must be written out first.
2. That labour grows with the index.
3. The process becomes more difficult if we need expansions involving still larger powers.
4. So the answer is larger powers get harder.
