`1^3+1^2+1+2^3+2^2+2+3^3+3^2+3+....3n terms=`

Find the sum of n-terms: [(1/1)+(1^3 +2^3)/2 +(1^3 +2^3 +3^3)/3+....to n -terms

((1)/(2), (2)/(2) )/(1^3) + ((2)/(2) , (3)/(2) )/( 1^3 + 2^3) + ((3)/(2) , (4)/(2) ) / (1^(3) + 2^(3) + 3^(3) ) + ..... n terms

1^(3) + 1^(2) + 1+2^(3) + 2^(2) + 2+3^(2) + 3^(2) + 3+3… 3n terms =

If 1/1^3 + (1+2)/(1^3+2^3)+(1+2+3)/(1^3+2^3+3^3) +.......n terms then lim_(n->oo) [S_n]

(1^(2) )/( 1) + (1^(2) + 2^(2) )/(1+2) + (1^(2) + 2^(2) + 3^(2) )/( 1+ 2+ 3)+ …. + n terms =

The sum of (1/2 . 2/2)/(1^3) + (2/2 . 3/2)/(1^3 + 2^3) + (3/2 . 4/2)/(1^3 + 2^3 + 3^3) + ….. Upto n terms is equal to

If ( 1^2 + 2^2 + 3^2 + ……………… to 'n' terms) / ( 1.3 + 2.5 + 3.7 +……………. To 'n' terms) = 9/5 find 'n'.

If ( 1^2 + 2^2 + 3^2 + ……………… to 'n' terms) / ( 1.3 + 2.5 + 3.7 +……………. To 'n' terms) = 17/16 find 'n'.
