∑ k^2 - how to read this please? thanks
k=1

Answer 1

it is read as summation k=1 to 4 k^2

Answer 2

This is a summation notation. I usually read it as the following:
```
The sum of all integer “k”s from 1 to 4 in the function k^2.
```

Answer 3

that's just a shortcut way of writing 1^2 + 2^2 + 3^3 + 4^2

Answer 4

oops ,, i mean 3^2...

Answer 5

Or as @dpaInc said, you can just say it like this:
```
1^2 + 2^2 ... till ... 4^2
```
