| |  Exponent Pyramid
My teacher gave us a pyramid pattern to solve the coefficients of large exponents and then a pattern for the rest of the letters and their exponents but I can't for the life of me understand/remember what he said. I am specifically stuck on (a+b)^4.
Pyramid:
............1
..........1...1
........1...2...1
......1...3...3...1
....1...4...6...4...1
1...5...10...10...5...1 |

So based on that do I have this correct?
a^4 + 4a^3*b + 6a^2*b^2 + 4a*b^3 +b^4 |
