Solution :
Given, n = 2025

First of all (n-1).(n+1) = n^2 - 1
Now (n^2 - 1). n = n^3 - n

Now simplify,

n^3 - n + n = n^3
Now cube root of n^3 will be n
So the answer is n which is 2025

❤ Thank you
This made me laugh with joy and happiness

[AarushJEE-vk]

My approach was:
- Taking 2025 common, substituting 2024 and 2026 with (2025-1) and (2025+1)
Simplifies to-
[2025{2025.2025 - 1.1 + 1}]^(1/3)
[2025.2025.2025]^(1/3)
'.' represents multiplication operator

Thanks to 3b1b for introducing Manim which made all of our understanding better in math

It looks confusing at first, but the second time it becomes simple

[borntolearn]

Let x= 2024
2025= x+1
2026= x+2
Put the values you will get (x+1) ^3
Hence taking cube root = x+1 = 2025(Ans)

He just made math a whole a lot easier in the future for me since I’m in 6th grade

For all the people saying what’s the point, I can just use a calculator. This question isn’t testing your arithmetic skills. It’s testing your problem solving skills, and how you can take this problem and simplify it. It’s an incredibly useful skill not just in other areas of mathematics, like proving things in real analysis, but also life.

I love this one
It matches with the beat

[gauranshvarshney]

Take x = 2025
2026=x+1 and 2024=x-1
Take x common, expression becomes [(x-1)(x+1)+1]*x = (x^2-1+1)x = x^3, so cube root of x^3 = x = 2025

well we know that n(n+1)(n+2)+(n+1)+(n+1) is how the expression inside the cube root would be written
multiply out n(n+2), giving you (n^2 + 2n)
so you have (n+1)(n^2 + 2n)+(n+1)
factoring out (n+1), we get, (n+1)(n^2 + 2n +1)
we know that (n+1)^2=n^2 +2n+1
so it can be written as (n+1)(n+1)^2
or, (n+1)^3
since theres a cube root, the cube and root cancel(i know that the cube root of anything yields 3 values but the other two are imaginary, which is why we're sticking with the principal value)
so the final product is n+1, which in this case is 2025
the explanation might make you think this is a long process, but doing it in your head is split second processes

[rishavjain]

Easy just write 2024 as 2025-1, 2026 as 2025+1 and solve it's answer is 2025

kinda goofy seeing variables on youtube, i don't see them much here
though ty for the vid

This was actually a question on UKMT Intermediate Challenge 2025! I remember just doing it using the numbers instead of substituting them for n, though.
