Question
1. A primitive Pythagorean triple is an ordered tripe of integers (x, y, z) such that
x² + y? = z?,
where x, y and z are pairwisely relatively prime integers. Determine exactly 10 primitive Pythagorean
triples and be able to exhibit that they satisfy the given equation.
2. Solve the system of congruence
3x + 7y = 10 ( mod 16)
5x + 2y = 9( mod 16) .
Hint: Eliminate x by multiplying each congruence a suitable constant and then adding them to form a
linear congruence containing only y as a variable. Likewise, eliminate y by multiplying each congruence
a suitable constant and then adding them to form a linear congruence containing only x as a variable.
3. Prove that if n is a triangular number, then so are 9n + 1, 25n + 3, and 49n + 6.
Hint: Recall that in the formula for finding the n-th triangular number, the numerator is a product of two
consecutive integers.
4. A palindrome number is a number that remains the same when its digits are reversed. For example, the
following numbers are palindromes:
7 22 131
5665 10 901
480 084.
Show that a palindrome with an even number of digits is divisible by 11. Hint: Read your notes.
