If the sum ` sum_(n=1)^10 sum_(m=1)^10 tan^(-1) (m/n) = k pi`, find the value of k

If sum_(n=0)^(oo)2cot^(-1)((n^(2)+n+4)/(2))=k pi then find the value of k

If sum_(n=0)^(oo)2cot^(-1)((n^(2)+n+4)/(2))=k pi , then find the value of k.

Find the value of sum_(p=1)^n(sum_(m=p)^n^n C_m^m C_p)dot And hence, find the value of (lim)_(nvecoo)1/(3^n)sum_(p=1)^n(sum_(m=p)^n^n C_m^m C_p)dot

The value of sum_(r=1)^(n+1)(sum_(k=1)^(n)C(k,r-1))=

Find the value of sum_(p=1)^n(sum_(m=p)^n.^nC_m.^m C_p)dot And hence, find the value of lim_(n->oo)1/(3^n)sum_(p=1)^n(sum_(m=p)^n.^n C_m.^m C_p)dot

Find the value of sum_(p=1)^n(sum_(m=p)^n.^nC_m.^m C_p)dot And hence, find the value of lim_(n->oo)1/(3^n)sum_(p=1)^n(sum_(m=p)^n.^n C_m.^m C_p)dot

Find the value of sum_(p=1)^(n)(sum_(m=p)^(n)C_(m)^(m)C_(p)) And hence,find the value of lim_(n rarr oo)(1)/(3^(n))sum_(p=1)^(n)(sum_(m=p)^(n)C_(m)^(m)C_(p))

The value of sum_(n=1)^(10) n is:
