For each of the prime numbers in the table below: (a) Find the remainder when the prime number is divided by 4; and (b) Find whether the prime number can be expressed as the sum of two square numbers. If the prime number can be expressed as the sum of two square numbers, state the two square numbers. If the prime number cannot be expressed as the sum of two square numbers state “Not possible”. Complete the table below. The first two rows have been completed for you. Prime number The remainder when the prime number is divided by 4 Can the prime number be expressed as the sum of two square numbers? 3 3 Not possible 5 1 \[1^{2}\] + \[2^{2}\] 7 11 13 17 What is the link between whether a prime number can be expressed as the sum of two square numbers and the remainder when that prime number is divided by 4? If you are not sure you can extend the table above and see what happens for other prime numbers. The first proof that this pattern is true for all prime numbers was claimed by Pierre de Fermat and is called Fermat’s Christmas Theorem (because Fermat’s claim was dated December 25, 1640).Circle “YES” for each of the following prime numbers that can be expressed as the sum of two square numbers.Circle “NO” for each of the following prime numbers that cannot be expressed as the sum of two square numbers.You do not need to find the two square numbers. Prime number Can the prime number be expressed as the sum of two square numbers? 58 031 YES NO 58 043 YES NO 58 049 YES NO 58 057 YES NO Time is Up! Time's up
