Part 2 1) A prime number is an integer w**H **ich can only be divided by himself and the number "1". 2) A perfect **s **quare number is an integer that can be express**ED ** as the square of a natural numbers. 3) We say that "A" divides "B" if the number "B/A" is an integer. 4) We say that two polynomials A= a0 + a1X + ... +anXe(n) and B=b0 + b1X + ... + bnXe(n) are equal if all the ai=bi for all i=1....n. 5) A elementary row operation over a matrix A is one of the follow: - Switch the positions of two rows. - Multiply one row for a scalar K (wich cannot be 0). - Add one row with another.
