Question
Find the number of terms in the expansion of each expression.$$\left(\sum_{i=-2}^{5} a_{i}\right)\left(\sum_{i=-1}^{3} b_{i}\right)\left(\sum_{i=0}^{4} c_{i}\right)$$
Step 1
- The first sum is \(\sum_{i=-2}^{5} a_{i}\). The index \(i\) runs from \(-2\) to \(5\), inclusive. The number of terms is \(5 - (-2) + 1 = 8\). Show more…
