Answer:
∑ k³ and k from 2 to n.
Explanation:
Given : 8 + 27 + 64 + 125 + ... + n³.
To find: Write the sum using summation notation, assuming the suggested pattern continues.
Solution : We have given
8 + 27 + 64 + 125 + ... + n³.
We can write it in form of cube.
2³ +3³ +4³+5³+ ......n³.
So, the numbers is start from 2 to n.
We can write in summation form .
∑ k³ and k from 2 to n.
Therefore, ∑ k³ and k from 2 to n.
