1. [12 pnts.] Write each of the following using summation or product notation: 2. [8 pnts.] Expand the following : 3. [10 pnts.] Use induction to prove the following. Make sure you clearly specify each step in the
appropriate
area. The statement to be proved is that Base Case:(n = 1) by substituting a 1 for every n on the left side by expanding the summation its one term =================== 31 − 1 by sustituting a 1 for every n on the right side = 3 − 1 = 2 Inductive Hypothesis:(n = k) Inductive Step :(n = k + 1) Show: Proof: the left hand side of the equality we want to prove by splitting the sum by expanding the sum on the right its one term by the induction hypothesis by combining like terms by adding exponents on the 3’s QED
