Exercise 4.1 2. Establish each of the following for all n ≥ 1 by the Principle of Mathematical Induction. Solution a) S(n): ==‚ S(1): = = =1‚ So S(1) is true. Assume S(k): = Consider S(k+1) = = +=-1+= -1. Hence‚ it follows that S(k)⇒S(k + 1) is true for all n ∈ Z+ by the Principle of Mathematical Induction. b) S( n) for n=1‚ = 2 = 2+(1-1). So S(1) is true. Inductive Step: assume S(k)is true‚ for some (particular) k ∈ Z+—that is‚ assume that =2+(k-1). For n=k+1‚ = + (k+1)

The date of birth I used was mine 7/19/86 I will now do all three question that was asked a = 7 b = -19 c = 86 The INTEGERS above are needed to solve each given expressions. A) A^3 – B^3 (7^3) – (-2^3) 343-(-6859) =7‚202 This is the given expression with VARIABLES A and B and raised to the EXPONENTS of 3 on each of them. By substituting the integers in the variables and raising them to the 3rd power gives the answer of B) (a – b)(a2 + ab + b2) (7-(-19) (7^2+(7)(-19)+(-19^2)

DeVry University DeVry University was opened in Chicago by Dr. Herman DeVry in 1931. It was called DeForest Training School to prepare students for technical work in electronics‚ motion pictures‚ radio and later‚ television. It was in Chicago. In the 1940’s during WWII‚ DeVry University was selected by United States to educate Army Air Corps instructors on electronic devices. It was one of the first schools to be approved under the original G.I. Bill. In 1953 DeForest Training School became DeVry
