Answer:

print(num * 8)
Explanation:
num is just a variable could be named anything you want.
if code was like this num = input("enter a number:")
and do a print(num * 8)
we get an error because whatever the user puts in input comes out a string.

therefore: num = int(input("enter a number:"))
will allow us to do print(num * 8)
