Answer: 1111

Explanation: As a decimal number can be decomposed in a sum of products involving powers of ten, it can be factored as a sum of products of powers of 2 in order to convert to binary.

In the example, we can write 15 as a decimal number in this way:

1* 10¹ + 5* 10⁰ = 15

Decomposing in powers of 2:

1*2³ + 1* 2² + 1*2¹ + 1.2⁰ = 1 1 1 1 = (15)₂

Can some one fix this <br> input ("Enter a number: ") <br> print (num * 8)

Kaylis [27]

If you save the input as num,
this will print the input 8 times.

num = input("Enter a number: ")
print(num * 8)

If you want to do actual math calculations,
then the input needs to be a number.

num = float(input("Enter a number: "))
print(num * 8)

This doesn't account for any errors in which the user doesn't input a number, but I don't think that's what you were looking for anyway :)
