I agree. Since the problem restricts answers to positive integers, just starting with 2 and checking each possibility is way quicker then the long method shown in this video.
I don´t agree completely with the assumption that (X+Y)*(X^2-YX+Y^2) = 1*35. Why not (X+Y)*(X^2-YX+Y^2) = 5*7 or (X+Y)*(X^2-YX+Y^2) = 7*5, for example. We can not force a result for an equation!!!
How long did that take? I did it in my head instantly and fast-forwarded to the end of the video to check if my solution was correct. It was, and I'm no mathematician.
Three, by inspection. Still, this puzzle and its RUclips have a valuable lesson for it: some fools are easily distracted, perhaps carrying with them the thought that they are doing something rarified or worthwhile as they go. The spelling gadget wants me to spell it with an e, "rarefied," which strikes me as inane. Checking with Google, I'm a bit surprised to find that Oxford want the idiotic "rarefied," which would obviously be the nonexistent word pronounced rair-fide, while the often shoddy Merriam-Webster crew agree with me on "rarified."
Intuitively, ask, what two perfect cubes, when added up, equal 35. The answer is 27 and 8. 27 is 3^3 and 8 is 2^3. X=3. Don't overthink things.

Plus, in order to know to multiple n by 3/3 at 0:30 , you have to already know the n = 3.

n = 3.
27 + 8 = 35.
N=3

Why unnecessary extra sound ?
