[4(1)/(5)-:{1(3)/(4)-(1)/(2)(3(1)/(2)-(1)/(4)-(1)/(6))}]

4(4)/(5)-:{2(1)/(5)-(1)/(2)(1(1)/(4)-(1)/(4)-(1)/(5))}

4(4)/(5)-:{2(1)/(5)-(1)/(2)(1(1)/(4)-(bar((1)/(4)-(1)/(5))))}

3log 2 +(1)/(4) -(1)/(2)((1)/(4))^(2)+(1)/(3)((1)/(4))^(3)-….. =

3log 2 +(1)/(4) -(1)/(2)((1)/(4))^(2)+(1)/(3)((1)/(4))^(3)-….. =

(-(1)/(2)-(2)/(3)+(4)/(5)-(1)/(3)+(1)/(5)+(3)/(4))/((1)/(2)+(2)/(3)-(4)/(3)+(1)/(3)-(1)/(5)-(4)/(5)) is simplified to

(7(1)/(2)-5(3)/(4))/(3(1)/(2)+?)-:((1)/(2)+1(1)/(4))/(1(1)/(5)+3(1)/(2))=0.6 a) 4(1)/(3)(b)4(1)/(2) (c) 4(2)/(3) (d) None of these

The value of 1 (2)/(3) +[16(1)/(2) - { 1 (1)/(10) (3(1)/(3) +5)}] 1/4 "of" 2 (1)/(2) xx 4 (4)/(5) is :
