2) (10 pts) An ordered triple of positive integers (a, b, c) is called a Pythagorean Triple if a² + b2 = c2. Prove that if m and n are positive integers with m > n, then (m? – nº, 2mn, m² + n°) is a Pythagorean triple. Use this...
2. Prove that if a and b are positive integers such that a is a factor of b, then any finite (terminating) mantissa of base a can be converted to a finite (terminating) mantissa of base b. Note: Express the number in summation form
Let a, b, c, and m be integers with c and m both positive. Prove that a ≡ b (mod m) holds if and only if ca ≡ cb (mod cm) does.

Find how many positive integers with exactly four decimal digits, that is, positive integers between 1000 and 9999 inclusive, have the following properties: (a) are divisible by 5 and by 7. (b) have distinct digits. (c) are not divisible by either 5 or 7.
consider two vectors A= -10i+20j, and B has a length of 15 and angle of +45 with respect to the positive x axis. What third vector C must be added to these two such that A+B+C=0?
