Hii shreya ☺️

Answer:

332640 ways

Step-by-step explanation:

Given

Word to be arranged = POLYHEDRA

in POLYHEDRA

Number of vowel (O,E and A)=3

Number of consonants = 6

total number of alphabet = 9

To find arrangements of alphabet when vowel is not together can be arranged first we have to arrange the vowel together .

OEAPLYHDR

Take OEA at unit place

Now total alphabet = 7

arrangements = 7!3!

Now

Number of arrangement of alphabet of word POLYHEDRA =9!

Number of way the vowel alphabet not arrange together = 9! - 7!3!

= 7!(72 - 6)= 7!*66 = 5040*66= 332640 ways
