Answer: 27783

Step-by-step 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 :-

$21\times21\times21=9261$

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 :_

$9261\times3=27783$

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