यदि `1+2+2^(2)+............+2^(n-1)=255` हो तो n = ................ होगा।

If 1+2+2^(2)+...+2^(n-1)=255 then find n

If the sum of 1+2+2^(2)+ . . . . . . . . . .+2^(n-1) is 255, find the value of n.

P(n) : 1^(2) + 2^(2) + 3^(2) + .......+ n^(2) = n/6(n+1) (2n+1) n in N is true then 1^(2) +2^(2) +3^(2) + ........ + 10^(2) = .......

यदि x^(2)+2=0 हो तो x का मान होगा-

If the sum 1+2+2^2+......+2^(n-1) is 255, then find the number of terms.

किसी घनात्मक पूर्णांक n के लिए यदि, (1)/(sqrt(4)+sqrt(5))+(1)/(sqrt(5)+sqrt(6)) +(1)/(sqrt(6)+sqrt(7)) +..... + (1)/(sqrt(n)+sqrt(n+1))=5 है तो n का मान क्या होगा?

(2^(n)+2^(n-1))/(2^(n+1)-2^(n))

Prove that ((2n+1)!)/(n !)=2^n{1. 3. 5 .........(2n-1)(2n+1)}

lim_ (n rarr oo) [(1+ (1) / (n ^ (2)))) (1+ (2 ^ (2)) / (n ^ (2))) (1+ (3 ^ (2) ) / (n ^ (2))) ...... (1+ (n ^ (2)) / (n ^ (2)))] ^ ((1) / (n))
