Question:
If f(x) = loga(loga x), then f'(x) is equal to
If f(x) = loga(loga x), then f'(x) is equal to
Options:
- loge a / x
- x / loge a
- loga e / (x loge x)
- loge a / (x loga x)
- loge a / x
- x / loge a
- loga e / (x loge x)
- loge a / (x loga x)
Correct Answer: a)
Explanation:
‘ We ha√e, f(z) = log, (log, z) ‘
f(@) = log, (log, z) ‘
! = goa (log, ©) 4; (log, z) !
‘ = = . dlog,e = re
‘ We ha√e, f(z) = log, (log, z) ‘
f(@) = log, (log, z) ‘
! = goa (log, ©) 4; (log, z) !
‘ = = . dlog,e = re
