Question

How many words can be formed with the letters
LOGARITHM? In How many of there are the
vowels together​

Answer 1

You are lucky that all the letters are different

Total words that can be formed is simply the permutations of all the 9 letters which are different of course in the word LOGARITHM

Now your answer is 9!

If vowels are to be together, then here first notice the vowels, they are O, A, I

Take it as a single letter OAI = x

Then remaining letters are only 9 - 3 = 6

So total permutations of 6 + 1 =7 letters is 7! and in each such permutations OAI as a single letter can further permutate in 3! ways

So your answer is of course 7!3!

Hey listen the answers are in your book

So why to waste your time here
