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

(1/2)^-2+(1/3)^-2+(1/4)^-2 =___

Find the value of : (1/2)^-2+(1/3)^-2+(1/4)^-2

Which of the following number is the greatest ? 2^(1/2), 3^(1/3), 4^(1/4), 6^(1/6

Value of (1-(1)/(2^(2)))(1-(1)/(3^(2)))(1-(1)/(4^(2)))dots(1-(1)/(85^(2)))

The greatest of the numbers 2^(1/2), 3^(1/3), 4^(1/4), 5^(1/5), 6^(1/6) and 7^(1/7) is

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)-….. =

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
