Find the sum of ∑3/k=0 k^2

Step-by-step explanation:

Given

Let's break down each part. The input at the bottom, in this case , is assigning an index at a value of . This is the value we should start with when substituting into our equation.

The number at the top, in this case 3, indicates the index we should stop at, inclusive (meaning we finish substituting that index and then stop). The equation on the right, in this case , is the equation we will substitute each value in. After we substitute our starting index, we'll continue substituting indexes until we reach the last index, then add up each of the outputs produced.

Since is our starting index, start by substituting this into :

Now continue with :

Repeat until we get to the ending index, . Remember to still use before stopping!

Substituting :

Substituting :

Since 3 is the index we end at, we stop here. Now we will add up each of the outputs:

Therefore, our answer is:

i you goofed up when writing this, because hnot is not a word minusf is not either. i cannot answer   because of that.
