`(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

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

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

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

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?

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

Which one of the following is not equal to (83)^(-(1)/(2))?(23)^(-(1)/(2))( b) 8^(-(1)/(6))( c) (1)/((83)^((1)/(8)))( d) (1)/(sqrt(2))

the value of ((2^((1)/(3)))(6)^((1)/(6)))/((3)^((1)/(6))(8)^((1)/(6)))
