X7. We know that given any real numbers x1 and x2, if x1X2 = 0, then x1 = 0 or x2 = 0. Since there are two factors, let's call this statement P(2). We assume P(2) is true without proving it. a. Use an inductive idea to carefully explain why given any real numbers x1, X2, and x3, if X1X2X3 = 0, then x1 = 0, x2 = 0, or X3 = 0. Be sure to use only P(2) in your argument. Hint: x,x2x3 = (x,X2)X3, which consists of two factors, x1X2, and x3. b. Use an inductive idea to carefully explain why given any real numbers x1, x2, X3, and x4, if X1X2X3X4 = 0, then x1 = 0, x2 = 0, x3 = 0, or x4 = 0. Be sure to use only P(2) or P(3) in %3D %3D your argument. c. Let P(n) be the statement that given any n real numbers X1, X2, ...,Xxn, if X1X2 Xn = 0, then x; = 0 for some i. Use mathematical induction to prove P(n) is true for all n 2 2. The base case does not need to be proven, but at least acknowledge its truth.
