23. (a) Find the first 3 terms in the binomial series of V5 - 2x. Use this to approximate the value of V3. (b) If the sum of the coefficients of all even powers in the product: (1 + x+ x2 + x3 + ... + x2n) (1 -x+x2 - x3 + ...+ x2n) is 101, find the value of n. (Hint: substitute x = -1 and x = 1 into the series)
