JavaScript beginner help

Hey guys, I have been studying JavaScript for 3 weeks already. I'm stuck with function and these 3 tasks. If anyone could help me I would really a...

What problems or difficulties are you finding when writing these functions?

this is the first solution, don't know how to settle cubic, even don't is this function right.

function sum(n,m){
let s = 0; //sum
for(let i = n; i<=m; i++){
s+= i;
}
return s;
}
let p = sum (5,6);
console.log(p);

You almost have it!

The cube of a number n is n³, which is n * n * n, so you would just need to change one line:

s+= i;

into this:

s+= i*i*i;

Alternatively, you could use the Math.pow function and do something like this:

s+= Math.pow(i, 3);

Or another option would be using the exponentiation operator (**) which is equivalent to Math.pow():

s+= i**3;

How about the second one? What errors do you get in the second exercise?

wow, THANK YOU! :D :D :D
My motivation is rising uppp

This is third, but code does not work... what do you think?

function divisible(n,m,k){
result = 1;
for(i = n; i <=m; i++){
if(i%k == 0){
result = result / i;
}
}
console.log(divisble);
}

divisible(1,50,4)

EDIT: second one I have no idea how to set up

You want to know the number of numbers that are divisible by k and are between n and m, right?

Why are you doing this result = result / i;?
