(a) Show that P(0) is true. (For each answer, enter a mathematical expression.) 1. Before simplifying, the left-hand side of P(0) is 2(0)=1 2. Before simplifying, the right-hand side of P(0) is (0+2)1=21=2 x Your answer cannot be understood or graded. More Info The fact that the statement is true can be deduced from that fact that 20 = 1. (b) Show that for each integer k 2 0, if P(k) is true, then P(k + 1) is true. (For each answer, enter a mathematical expression.) (1) Let k be any integer with k 2 0, and suppose that P(k) is true. In other words, suppose that 2^K
