For those, who are trying to get answer 18 in question 34!/37 when we apply the second formula. 35!/37 = +1 35 x 34! / 37 = +1 Since the remainder for 35 / 37 is -2 so we have to alter our positive remainder in RHS to negative remainder to get a positive integer which is -36. 34! / 37 =-36 / -2 = 18 Tada

That's a wrong explanation, since 35!/37 = +1 therefore 35 * 34!/37 = 37K + 1 -2 * 34!/37 = 37K+1 34!/37 = (37K + 1)/(-2) Now we consider smallest value of K to be divisible by 2. so K = 1 therefore 34!/37 = 38/(-2) = -19 or 18 [using negative remainder]

For some reason when I try to solve Remainder of (48)^(45) when divided by 35. I get correct answer as 13 if I use Chinese remiander theorem and the method explained by Ravi sir, but, when I directly apply Euler's remainder theorem here, I am getting wrong answer. How is that possible??

@skarde6969

Жыл бұрын

Firstly you need to check if X/B are both co - prime to each other and that they have nothing in common. After that you need to find out the Euler number of the denominator which is 35 here. if you solve directly by Euler it will be really difficult to diminish the powers which is why you might be getting an incorrect answer. Also, when we use chinese rem theorem we split the denominator into two prime numbers and then use Euler. ( 5*7) hope it helped.

Sir do we really need to remember all these theorems and methods?

But why do we always have to multiply K by nearest no. Possible... Like in 34!/37.. we took 37(1)-1÷2...why can't we take 37(3)÷2 ... Just want to know the logic behind taking the minimum value of k possible..

@anilbhai1652

4 жыл бұрын

To avoid one or more steps even after doing these much steps, suppose if you take k=3 then value will be 55 but it is still divisible by 37 then again you have to find remainder of 55/37 thats at the end will give you 18 as a remainder. So if you can avoid such one or more steps by just taking lowest value of K then who will do such stupidity to waste his/her time.

So remainder of (97! × 98)/101 = 101K + 50. Or (97! × -3 )/101 = 101K + 50 Or 97!/101 = -(101K + 50)/3 Find the value of K which is 2 So 97!/101 = -252/3 or -84 or 17.

Totally 17 times without leaving any remainder. If still not understand tell me what is the remainder of 10/2. Now your answer should be 5, is it ? No because 10/2 = 5×2/2, just cut the 2 with 2 and you get 5 as a remainder, according to you. No we must not cut the numbers.
