Question 287804
<font face="Garamond" size="+2">


Do you mean *[tex \Large (a+b)^8]?



If so, use the binomial theorem:



*[tex \LARGE \ \ \ \ \ \ \ \ \ \ (x\ +\ y)^k\ =\ \sum_{k=0}^n\ \left(n\cr k\right)x^{n-k}y^k]


where *[tex \LARGE \left(n\cr k\right)] is the number of ways to select *[tex \Large k] things from *[tex \Large n] things calculated *[tex \LARGE \frac{n!}{k!(n-k)!}]
