Answer» Answer: for n = 1 LHS = 1³ = 1 RHS = [ 1² (1 + 1)² ] / 4 = 4/4 = 1 which is TRUE SUPPOSE that n = k is true then 1³ + 2³ + 3³ + ... + k³ = [ k² (k + 1)² ] /4 now suppose that n = k + 1 is true LHS = 1³ + 2³ + 3³ + ... + k³ + (k + 1)³ =[ k² (k + 1)² ] /4 + (k + 1)³ = [ k² (k + 1)² + 4(k + 1)³ ] /4 = [ k² (k + 1)² + 4(k + 1)³ ] /4 = [ k⁴ + 2k³ + k² + 4k³ + 12k² + 12k + 4 ] /4 = [ k⁴ + 6k³ + 13k² + 12k + 4 ] /4 RHS = [ (k + 1)² (k + 2)² ] /4 = [ (k² + 2k + 1)(k² + 4k + 4) ] /4 = [ k⁴ + 6k³ + 13k² + 12k + 4 ] /4 LHS = RHS P(k) = P(k + 1) so by mathematical INDUCTION, the statement is true |
