Answer: 27783

Explanation:

Given : The number of toppings for pizza= 21

If repetition of toppings is allowed, then the number of different 3-topping combinations will be :-


21*21*21=9261

Also, the number of choices for crust = 3

Then, the number if different 3-topping pizzas can be made if toppings can be selected more than once will be :_


9261*3=27783

Hence, the number of different 3-topping pizzas can be made = 27783
