this is where i make lots of mistake but finally i think my probablity of doing mistake might be reduced after watching your video sir

Still didn't get it. +2^18 and -2^18 becomes opposite and then should be eliminated that gives 0 . And only 2^1 should be left. Can Anyone please explain how the answer is 2^18?

i like the background music. It sounds very cool and mysterious

This helped a lot, thank you very much you're the best!!!

Thank you so much! This really helped me, I finally found a viedo that I understand😊

Try 2^4 - 2^2 shows that the answer doesn't always comes out as a single exponent number, the answer for this is 12...

Why and how did u get that -1 for the •(2 - 1)??

I notice a pattern in the case of 2^n -2n-1 the answer is 2^n or more specifically 2^n x 1 ( 1 is 1 less than 2)
in the case of 3^n - 3^n-1, the answer is 3^n-1 x 2
in the case of 4^n- 4^n-1, the answer is 4^n-1 x 3 . so 4^4- 4^3 should = 64x3 or 192 . 4^4=256 and 4^3=64
256-64= 192 or 64x3
I am claiming that in the case of 5^n - 5^n-1 the answer is 5^n-1 x 4. So 5^6 - 5^5 should = 5^5 x 4
5^5+1 - 5^5 = 5^5 (5-1) =5^5 x 4
So it is true that 12^6 - 12^5 = 12^5 x 11? (notice 11 is one less than 12). and I just found it is?
So my theory is P^n - P^n-1 = (P^n-1)(P-1) in which P and n are positive integers .
so 100^2 - 100^1 should = 100^1 x 99 or 9900. let me check 100^2= 10, 000 , 100^1=100, and 10, 000-100=9900

Very clear explanation. Thanks for sharing………

[JustElcy]

helped me alot
thank you God bless you

This doesn't make any sense to me wouldn't it just be 2^1?

Eea mejor factorizar de forma directa por 2^18(2-1)

[devondevon]

I say the answer = 2^18 why?
because when I do 2^1- 2^0= 2-1= 1 or 2^0 or the subtrahend AND 2^2-2^1= 4-2=2 OR 2^1 or the subtrahend AND 2^3- 2^2 = 8-4 OR 2^2, or the subtrahend All three is just one apart (eg 2^2- 2^1) just like the problem (2^19-2^18
as 19 is just one less than 18)) and the answer is always the SUBSTRAHEND. So I see a PATTERN and will assume FOR NOW it is true for all. So the answer is 2^18

If it is 10^15 - 10^16, would the answer be 10^15? just having lil trust issues with my own works hehe

Ohhhh my god I search for like this topic I found a video with 135k view but it was click bait but your video is not click bait but I do not understand why your non clickbait video has less veiw than a Cickbait one? You should have over 30millions

[jesusjhonruiz]

why does it feel like I'm on being being illusionated???

[hulkhulkspider]

So, for example, if my problem was 3^2013 - 3^2012, would the answer be = (2) 3^2012? Pls and thanks
