Yes, at 8:24, Problem 1b should be 16. Sorry for the mistake and thank you for pointing it out!
Bobo
thanks pookie
Nicely and calmly explained.Thank you, Sir.
man, you're genius!!! The best method ever!!!
thanks for the video. quite helpful approach!
Excellent work Sir 🙏🙏🙏
Excellent explanation. Thank you.
the correct answer should be x=16(mod26) Thank you for such a clear representation. Even if you add positive 26 the answer is just same.
I like the way you explain everything.
Thank so much ...This Video Helped me For Exam time...in 5x=2is 16 not 15 ...sry For Pointing..u
Thankyou. It helps me a lot
Why did we subtract in the first two questions and then added the mod to our integer b on the last question
Watch at 1.25 speed. Good video, thanks!
;)
You're the GOAT and a Lifesaver with that one lol
Kindly make an other video for reaiming questions of problem 4.4 page no 82 itx my humbaly request
How we can show that 89 | 2^44 - 1 ????
Can you help me with this, please:x ≡ 2 (mod 11)x ≡ 9 (mod 15)x ≡ 7 (mod 9)x ≡ 5 (mod 7) ?
((d divide n) and (a ≡ b (mod n)) ==> (a ≡ b (mod d))x ≡ 9 (mod 15) ==> x ≡ 9 (mod 3) x ≡ 0 (mod 3)x ≡ 7 (mod 9) ==> x ≡ 7 (mod 3) x ≡ 1 (mod 3)It is impossible.
25X=15 mod29 ------------(1)---------------------------- 4X=15 mod29 ------------(2)(1) + (2)X6X=105=18 mod29Ans. 18
how (2) come?
I think you meant x is congruent to 16mod26 in 1.b
Thanks
At 8:00 we cant divide by 5 because (26 notre prime )
We can divide, cause 5 and 26 are coprime
I don't see the down side because the text is hide the board
Wonderful! Explained in simplest way. Sir, can you explain 34x≡60 (mod 98) using same technique?
Since 98 is not prime, then this method is invalid
@@doctorscalling9479 21 is not a prime either
• Step 1 - Divide both sides by 217x = 30 (mod 49)• Step 2 - Express 30 (mod 49) as -68 (mod 49)17x = -68 mod (49)• Step 3: Divide by 17x = -4 (mod 49) = 45 (mod 49)
Adding 26 to -10 is 16 not 15
15 or 16
8:24 did you mean 16?
yes it';s 16 :D
