How many ways can the letters in the word D-I-N-O-S-A-U-R be arranged?

40,320 ways

Step-by-step explanation:

To find the number of ways that the letters can be arranged, as all letters are different, we just need to find the factorial of the number of letters.

As we have 8 different letters, the number of ways is:

Factorial (8) = 8*7*6*5*4*3*2 = 40,320 ways

We can arrange the letters in 40,320 different ways.
