If `sumn=210`, then `sumn^2=`

If sum n=210 , then sum n^2 is equal to:

If sum n^2=2870, then sumn^3= (A) 44100 (B) 48400 (C) 52900 (D) none of these

If sumn=55 then sumn^2=

If sumn = 55 then sumn^2 . = ...............

If sum n=210 then find the value of sum n^(2)

If Sigma n = 210 " then " Sigma n^(2) =…….

If sumn ,(sqrt(10))/3sumn^2,sumn^3 are in GP, then the value of n is

If (n+2)! = 210(n-1)! , then the value of n is

If S_(1) = sumn, S_(2) = sumn^(2), S_(3) = sumn^(3) then lim_(n rarr oo) (s_(1)(1+s_(3)/8))/(s_(2)^(2)) =
