`(1/3^4)^(1/2)`

The sum of the first 35 terms of the series (1)/(2)+(1)/(3)-(1)/(4)-(1)/(2)-(1)/(3)+(1)/(4)+(1)/(2)+(1)/(3)-(1)/(4) is -(1)/(2)(b)-(1)/(4) (c) (1)/(4) (e) None of these

The sum of the first 35 terms of the series (1)/(2) + (1)/(3) -(1)/(4) -(1)/(2) -(1)/(3) +(1)/(4) +(1)/(2) + (1)/(3) -(1)/(4)

The square root of ((1 3/4)^4-(2 1/3)^4)/((1 3/4)^2-(2 1/3)^2)

If S=(1)/(2)((1)/(2)+(1)/(3))-(1)/(4)((1)/(2^(2))+(1)/(3^(2)))+(1)/(6)((1)/(2^(3))+(1)/(3^(3))) then S=

Sum of the series (1)/(2)((1)/(2)+(1)/(3))-(1)/(4)((1)/(2^(2))+(1)/(3^(2)))+(1)/(6)((1)/(2^(3))+(1)/(3^(3)))-... is

Sum of the series (1)/(2)((1)/(2)+(1)/(3))-(1)/(4)((1)/(2^(2))+(1)/(3^(2)))+(1)/(6)((1)/(2^(3))+(1)/(3^(3)))+...oo

If ((3(1)/(4) )^(4) -(4( 1)/(3))^(4))/( (3,(1)/(4) )^(2) -(4,(1)/(3))^(2) )= ((13a)/(12))^(2) , find a.
