Question

Generate the coefficients that would be used to expand (a+b)^7 by using binomial expansion.

Answer 1

You can either use the combination formula n C r = (n!)/(r!*(n-r)!)

where in this case n is fixed at n = 7 and r ranges from r = 0 to r = 7

or you can use pascals triangle and look at the row that starts with 1, 7, ...,

Answer 2

That doesn't really make sense?

Answer 3

have you heard of pascals triangle before?
