I'd just go,"well, 6 is the closest to 854"

@kckcmctcrc

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?

@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 💀

@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
    —
  144

It's fun learning the terms in math in English. Your channel is great

@marianorodriguez13

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.

@Fillster

I didn’t even know what a units digit was

@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.

@NastyG27

I can’t wait to use this in the real world!

@Crazy33749

I'm actually enjoying math with this guy

@nishchaysharma5904

When life is less about solutions but more about patterns.

@islamictv6475

If even power of 4 = unit digit 4
If odd power of 4 = unit digit 6

@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!

@JJ_TheGreat

Brilliant! I never would have picked up on this pattern! Thank you!

“Hmm, I haven’t picked D in a while so…”

@Impractical-nd1ss

I still get SAT prep videos after all these years. I need GRE prep videos now.

@pradap2298

I need reincarnation to learn math  again

한국에선 문제를 풀고 답을 고르는데 답으로 문제에 접근하는 모습이 새롭네요
