Question 12

Indices and Logarithms

If V = P logx (M + N), express N in terms of X, P, M and V.

  1. A.N = XV/P − M
  2. B.N = XP/V − M
  3. C.N = XV/P + M
  4. D.N = XP/V + M
Show the answer and explanation

Answer: A (N = XV/P − M)

Explanation

log_x(M + N) = V/P, so M + N = x^(V/P) and N = x^(V/P) − M.
