Step-by-step explanation:
given that 20 different comic books will be distributed to five kids.
Also given that there are no restrictions on how many go to each kid (other than the fact that all 20 will be given out)
Hence each kid can get any number of books and there is no chance a kid does not get any book also.
There are 5 kids.
Take the first book. It can be given to any one of the 5 kids in 5 ways
Now second book can be similarly given to any one of the 5 kids in 5 ways
this continues for all 20 books
Total no of ways =![5*5*...20 times\\= 5^{20} \\=9.53674E+13](/tpl/images/0407/3164/76f70.png)
