I am pretty weak at questions involving some sort of summation and this one is really confusing me and its solution isn't helping
#Can anyone please help me make sense of this problem and its solution?

<@715786738198380574> what isnt clear
The 1/4 part
How did it resolve it into whatever the numerator became
halcyon snow
the formula is (0.5n(n+1))^2
mossy monolith
the formula is (0.5n(n+1))^2
Oh there's a direct formula for it?
halcyon snow
yes there exists
mossy monolith
I see
Thanks a lot man, I was pretty stuck on this problem
Really appreciate it
mossy monolith
Yep I'll note it down for future use cases
halcyon snow
now after step 1 of 1/4's multiplication we divide both numrator and denominator with n^4
so as to get it into a much simpler form as shown in the last step where 1/n is present

I didn't really have interest in it either

but then why did u choose engineering
I thought it would be something I would like, I took up mechanical

But yeah it just feels like it'll be a rat race all over again like jee and boards and what not
mossy monolith
u couldhve gonr to neet or some bio related field like biotechnology
I was gonna do that
halcyon snow
right
mossy monolith
But through state entrance exams I got engineering and I kinda just went with it
