Question

express each sum using summation notation. Use 1 as the lower limit of summation and i for the index of summation :1^2+2^2+3^2...+15^2

Answer 1

Given the summation:

1² + 2² + 3² + ... + 15²

Let's express the sum using summation notation.

Let's use 1 as the lower limit and i for the index of summation.

To write the summation notation of the given expression, we have:

$\sum_{n\mathop{=}1}^{15}n^2$

Here, we. have 15 numbers.

This means the number of terms is 15.

The lower limit is .

Thus, we have: n = 1.

Therefore, the summation notation for the expression is:

$\sum_{n\mathop{=}1}^{15}n^2$

ANSWER:

$\sum_{n\mathop{=}1}^{15}n^2$
