lim_(x rarr1)((x+x^(2)+x^(3)-x^(n))-n)/(x-1)

If lim_(x rarr 1)((x+x^2+x^3+....+x^n-n)/(x-1))=820 , then find n.

If lim_(x rarr 1)((x+x^2+x^3+....+x^n-n)/(x-1))=820 , then find n.

lim_(xto1)(x+x^(2)+x^(3)+…….+n^(n)-n)/(x-1) =……….,where n in N

lim_(x rarr1)((1-x)(1-x^(2))...(1-x^(2n)))/({(1-x)(1-x^(2))...(1-x^(n))}^(2)),n in N, equals ^2nP_(n)(b)^(2n)C_(n)(c)(2n)!(d) none of these

If lim_(xrarr1)(x+x^2+x^3+....+x^n-n)/(x-1)=5050 , then n=

The value of lim_(x rarr 1) (x+x^2+...+x^n-n)/(x-1) is

lim_(x rarr1)(x^((1)/(n))-1)/(x^((1)/(m))-1)(m and n are integers is equal

lim_(x rarr0)((x+1)^(n)-1)/(x)
