0.3 + 0.003 + 0.00003 + .... ধারাটির অসীম পর্যন্ত যোগফল-
Solution
Correct Answer: Option A
0.3 + 0.003 + 0.00003 + ....
প্রথম পদ, a = 3/10
সাধারণ অনুপাত, r = 0.003/0.3
= 1/100
যোগফল = a/(1 - r)
= (3/10)/(1 - 1/100)
= (3/10)/(99/100)
= 10/33
প্রথম পদ, a = 3/10
সাধারণ অনুপাত, r = 0.003/0.3
= 1/100
যোগফল = a/(1 - r)
= (3/10)/(1 - 1/100)
= (3/10)/(99/100)
= 10/33
