Question
Find the indicated term in each expansion.$\left(x+\frac{1}{2}\right)^{8} ;$ fourth term
Step 1
Step 1: The general term of a binomial expansion is given by ${n \choose r} a^{n-r} b^{r}$ where ${n \choose r}$ is the binomial coefficient, $a$ and $b$ are the terms of the binomial and $r$ is the term number minus 1. Show more…
