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

create table command is used to create a table named 'persons' with five columns which are labeled :
person I'd : whose data type is an integer
last name column with a variable character data type with maximum length of 255
first name column with a variable character data type with maximum length of 255
address column with a variable character data type with maximum length of 255
city column with a variable character data type with maximum length of 255
The VARCHAR data type is ideal since we expect the column values to be of variable length.
