If o x 1, then find the sum of the series log(1 x log (1+ x log(1 x to n terms log(1

(1)/(x log x log (log x ))

2log x-log(x+1)-log(x-1)=

(1)/(x.log x.log(log x))

int (1+log x)/(1+x log x)dx=

Solve the equation log(x+1)+log(x-1)=log3

If sum of the first 21 terms of series log _((1)/( 9 ^(2))) x + log _((1)/(9 ^(3))) x + log _((1)/( 9 ^(4))) x + ..., where x gt 0 is 504, then x is equal to :
