You're on a roll — This problem asks to prove an identity in financial mathematics. Based on the image, we need to prove that the expression on the left, which appears to be a "dual rate" formula, is equal to the expression on the right, which is a "single rate" formula. Let's interpret the expressions from the image: Left Hand Side (LHS): (1)/(i) + (S')/((1+S')^n - 1) Right Hand Side (RHS): (1 - PV)/(i) The previous question established S' = i. Let's apply this assumption here. Also, in financial mathematics, the present value of an ordinary annuity
