Here,

Let arrange the words in vowels and consonants

Vowels:: AIA

consonants : MXM

Vowels can be arranged in = \(\frac{(3!)}{(2!)} = 3\) (it is divided by 2! since vowel A repeats twice)

Similarly, consonants can be arranged = \(\frac{(3!)}{(2!)} = 3\) (it is divided by 2! since consonants I repeats twice)

Now, these arrangement can be arranged in 2 ways::

V V V C C C
OR
C C C V V V

Hence, the number of ways it can be arranged = \(2 * 3 * 3 = 18\) ways
