(6^(-1)-8^(-1))^(-1)

Find the value of x so that (2^(-1)+4^(-1)+6^(-1)+8^(-1))^(x)=1

Find the value of a if 2^(-1)+4^(-1)+6^(-1)+8^(-1)hat a=1

Evaluate ((0.6)^(0)-(0.1)^(-1))/(((3)/(8))^(-1)((3)/(2))^(3)+((-1)/(3))^(-1))

The value of the product 6(1)/(2)6(1)/(4)6(1)/(8)6(1)/(16)............ up to infinite terms

7(1)/(8)-6(1)/(10)

If (1 + (1)/(2)) (1 + (1)/(4)) (1+(1)/(6))(1+(1)/(8))(1-(1)/(3))(1-(1)/(5)) (1-(1)/(7))=1 +(1)/(x) then what is the value of x ?

If (1+1/2)(1+1/4)(1+1/6)(1+1/8)(1-1/3)(1-1/5)(1-1/7)=1+1/x ,then what is the value, of x? यदि (1+1/2)(1+1/4)(1+1/6)(1+1/8)(1-1/3)(1-1/5)(1-1/7)-1+1/x हो, तो x का मान क्या है?

{:("Quantity A","Quantity B"),((1)/(4)-(1)/(5)+(1)/(6)-(1)/(7)+(1)/(8),(1)/(4)):}

Sum the series : tan^(- 1)(4/(1+3.4))+tan^(- 1)(6/(1+8.9))+tan^(- 1)(8/(1+15.16))+............oo is :
