How to 1/0=infinity

Posted by Adarsh Tanty 2 years, 9 months ago

3 answers

Assume that you have 4 friends with you. You don't have any car, but you want to distribute the cars you have, among them equally. Will it be possible? No, because you cannot share something that does not exist in the first place.

Priyanshu Singh 2 years, 9 months ago

assume that √5 is rational number √5=a/b (here 'a' and 'b' are co prime) b√5= a Square on both sides (b√5)^2 =(a)^2 5b^2 = a^2.............(i) If a^2 is divisible by 5 than it means that 5 is also divisible by a. Now, let there be another integer 'c' therefore, a=5c square on both side a^2 =25c^2 5b^2 =25c^2 {from equation (i)} then, b^2 =5 c^2 b^2/5 = c^2 If b^2 is divisible by 5 than it means b is also divisible by 5 . Therefore 'a' and 'b' has common factor 5 . But , we ensure that 'a' and 'b' are co prime. Therefore, our assumption is wrong that √5 is rational number. Contradiction occurs. Therefore √5 is irrational numbers.

जय श्री राम🚩🚩 .... 2 years, 9 months ago

Here, S14 = 1050, n = 14, a = 10. We know that Sn = (n2)[2a+(n−1)d] Substituting the values we have, 1050=(142)[20+13d] ⇒1050=140+91d ⇒910=91d ⇒d=10 Therefore, a20=10+(20–1)×10=200 i.e. 20th term is 200.
