Had to look up ‘Units digit’, have always called this the ‘ones digit’.
@jaezryl
The first problem I usually encounter as a non-native english speaker is figuring out math terminologies. Like, what the hell is Units digit?
@rosegocheva3309
It's fun learning the terms in math in English. Your channel is great
@shreyaghosh6246
a simple trick: just multiply the base to the last digit. here, it would be 4*4 = 16. hence, 6 is in the unit's place. This helps because in Multiplication the last digit doesn't change. For example:
12
* 12

24
+120

Its clear that it is enough to check what happens mod 5, then: 4^854=(-1)^854=1 And the only possibility which is 1 mod 5 is 6.
@anderslvolljohansen1556
4^854 = 16^427 Since 6×6=36, any time you multipy two integers that end with digit 6, the product will also end with 6. Multiplying the product by a third integer ending with 6 must therfore also result in a new product ending with 6, etc. 4^854 = 16^427 is the product of 427 integers all ending with digit 6 and must therefore also end with digit six.

I swear I'm learning more in YouTube shorts than in school 💀
@Fillster
I didn’t even know what a units digit was
@islamictv6475
If even power of 4 = unit digit 4 If odd power of 4 = unit digit 6

When life is less about solutions but more about patterns.
@JJ_TheGreat
Brilliant! I never would have picked up on this pattern! Thank you!

I need reincarnation to learn math again
@Crazy33749
I'm actually enjoying math with this guy
@NastyG27
I can’t wait to use this in the real world!
@somethingbanter
When you start thinking of it as a logic puzzle instead of a math problem that is the secret to solving a lot of math problems.
@RealRabidRabbit
I used to not like math at all. Now that I'm far beyond math in my studies, seeing these shorts every so often is actually very interesting!
@MasterYoist
What the test makers are really looking for in these types of tests is an understanding of various concepts. One glance at these problems should enable the person being tested to get the correct answer within seconds without ever needing to guess.
@Abrushtofrin
Bro, you are teaching me stuff that I will use years later
@aniruddhjuyal67_17
Me being an Indian, calculated this in my mind🥱
