Answer:
num = int(input("enter a number:"))
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.
we cast int() around our input() function to convert from string to integer.
therefore: num = int(input("enter a number:"))
will allow us to do print(num * 8)
Answer:
6 address lines
Explanation:
The computation of the number of address lines needed is shown below:
Given that
Total memory = 64MB
= 
=
Also we know that in 1MB RAM the number of chips is 6
So, the number of address lines is 
i..e 26 address lines
And, the size of one chip is equivalent to 1 MB i.e. 
For a single 1MB chips of RAM, the number of address lines is
Therefore 6 address lines needed
