Now you just have to remember the numbers that this works for.

[MCAbdo]

I can't believe even you posted a video like this with a 'fake' solution method that only works on a few numbers

[PlanesAndGames]

So the cube root of 64 is equal to the cube root of 343, both of which are equal to 10... interesting!

[txvj]

Alright, I'm out. This is no longer about math education, it's become about mis-education. People are not only not learning from these, they're learning things that will almost always generate wrong answers. That's crossed the line from irresponsibility into active sabotage.

HAWKINGS CALM DOWN, YOUR WINDOWS MIGHT SHUT DOWN

[marwynnsworld]

Everything’s really easy except it’s harder to memorize the numbers that this works for

[maxhagenauer]

When you have tricks like these that only work for certain numbers, not even numbers under a specific category, it's probably not even worth memorizing cause you have to also memorized what specific numbers it works for.

[ayushadk]

What if the numbers are jumbled😂 the sum would be same but result will be different 😂

[ScarletEmber]

Ooohh
so then
³√1000 = 1+0+0+0 = 1
Thanks! I'll make sure to remember this trick!

[zunkman]

I'm surprised you're not showing us the "shortcut" to solving this in only 2 hours.

[ngocongnguyen]

this is not a trick, it's a coincidence

[wisdomlord]

Cube root of twenty-seven is equal to two added to seven which is nine but it is equal to three.
Thus, we have made a contradiction.
Hence, this method works for some numbers.

[AK-kzpe]

Every once in a fairly rare while, Paresh comes up with such pebbles among diamonds

[gaijininja]

Yeah, great and all, but the video creator knows as well as anyone who tried this technique on any other number, it only works on these specific numbers.

[_ErEn_-irtw]

This doesn't work for every issue, just one/two examples; 1. 8
2. 27

[johngamble]

First, i just want to post a giant NO!

Second, i assume there's a hard limit to the numbers that will work for, so the next question is, for what other combination of bases and numbers will that work?

[scmtuk]

What other powers does this work for? Well, I tried it for bases from 1 to 10, 000 and powers from 1 to 10, and these are the ones that work (other than 0 and 1 which will work for any power)
9^2, 7^4, 22^4, 25^4, 28^4, 36^4, 28^5, 35^5, 36^5, 46^5, 18^6, 45^6, 54^6, 64^6, 18^7, 27^7, 31^7, 34^7, 43^7, 53^7, 63^7, 68^7, 46^8, 54^8, 63^8, 47^9, 56^10, 57^10, 66^10, 67^10, 79^10

For example:
79^10 = 9, 468, 276, 082, 626, 850, 000 and if you add all those digits, it equals 79

[sia...]

Cube Root of 27 is 3 but according to your method it is 9.
Completely wrong. This method only works on certain number.

[tortillajoe]

Had a feeling these were Dudeney numbers

[uthoshantm]

A for loop in any programming language will unearth these numbers in no time.
