in the word LOGARITHM 


the position of vowels is 2,4,6


the position of consonants is 1,3,5,7,8,9


as their relative positions should be maintained 


the vowels can occupy only positions 2,4,6


and the consonants can only occupy positions 1,3,5,7,8,9


the permutation among vowels = 3!


the permutation among consonants =6!


thus total permutation = 6!*3!


=4320
