Write the sum using summation notation, assuming the suggested pattern continues. 8 + 27 + 64 + 125 + + n^3

∑ k³ and k from 2 to n.

Step-by-step 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.

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
