The binomial theorem states that (a + b)n = Σ (prbn_k. (a) Use the binomial theorem to show that 2k-0 W = 2n. (Hint, 2n= (1 + 1)n.) (b) Expand (a2 + b)4.
Using Taylor’s Theorem (and taking x0= 0), show that (for |x| << 1) (1+ x)n ≈ 1+ nx This can be especially useful for approximating the values of square roots, for which n = ½. (The full expansion of (1+x) n is sometimes called a binomial series, and the first order approximation a “binomial approximation.”)

1. Use the binomial theorem to show i) Ek_0 () = 21; ii) _o(-1)* (m.) = 0; and finally that the sum of the ( over odd k equals that over the even k and that both are 21-1. (Hint: for iii) add and subtract the results of i) and ii). For i) and ii) put x and y equal to suitable values in the binomial theorem). (15 points)
