Use Pascal's triangle to answer the questions below about binomial expansion and nCr. How many terms are in the expansion of (a+b)^8? A. 7 B. 8 C. 9 D. 10 E. 11
Added by Melissa R.
Step 1
We can use Pascal's triangle to do this. The 8th row of Pascal's triangle is: 1 8 28 56 70 56 28 8 1 These numbers represent the coefficients of the terms in the expansion of (a+b)^8. For example, the first term is a^8, which has a coefficient of 1. The Show more…
