What is the value of lim[n→∞] (1 - 1/n)ⁿ ?

  1. 0
  2. e⁻¹
  3. e^-n
  4. 1

Correct answer: e⁻¹

Solution

As n approaches infinity, the expression (1 - 1/n)ⁿ converges to e⁻¹, which is derived from the limit definition of the exponential function. This limit represents the continuous compounding of a decreasing quantity.
