Had to look up ‘Units digit’, have always called this the ‘ones digit’.
The first problem I usually encounter as a non-native english speaker is figuring out math terminologies. Like, what the hell is Units digit?
It's fun learning the terms in math in English. Your channel is great
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.
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
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.
Me being an Indian, calculated this in my mind🥱
I didn’t even know what a units digit was
I swear I'm learning more in YouTube shorts than in school 💀
When life is less about solutions but more about patterns.
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.
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!
Brilliant! I never would have picked up on this pattern! Thank you!
If even power of 4 = unit digit 4 If odd power of 4 = unit digit 6
Every odd one getting 4 and even power one getting 6
I can’t wait to use this in the real world!
I'm actually enjoying math with this guy
I need reincarnation to learn math again
In india class 7 th student preparing for olympiad solve this type of questions.
