<h2>The total number of ways = 1728 ways</h2>

Step-by-step explanation:

Given,

Math books = 4, History books = 3, Chemistry books = 3 and

Computer science books = 2

To find, the total number of ways = ?

∴ The total number of ways = 4! × 3! × 3! × 2!

= 24 × 72

= 1728 ways

∴ The total number of ways = 1728 ways
