If `y=a^(1/(1-(log)_a x))a n dz=a^(1/(1-(log)_a y)),t h e np rov et h a tx=a^(1/(1-(log)_a z))`

Text Solution

Verified by Experts

` log_(a) y = 1/(1 - log_(a) x)`
` rArr 1 - log_(a) y = 1 - 1/(1-log_(a) x)`
` = (-log_(a) x)/(1-log_(a)x)`
` or 1/(1-log_(a)y)=(1-log_(a)x)/(-log_(a) x)` ...(i)
` "But " z = a^(1/(1-log_(a)y))`
` rArr log_(a) z =1/(1=log_(a)y)=-1/(log_(a) x) +1`
` or 1/(log_(a)x) =1-log_(a)z`
` or log_(a) x = 1/(1-log_(a)z)`
` or x = a^(1/(1-log_(a)z)`
