Suppose Your Family Owns a Rare Book Whose Value T $V ( t ) = 8 e ^ { \sqrt { 0.6 t } }$

Short Answer

Suppose your family owns a rare book whose value t years from now will be $V ( t ) = 8 e ^ { \sqrt { 0.6 t } }$ dollars. If the prevailing interest rate remains constant at 6% per year compounded continuously, when will it be most advantageous for your family to sell the book and invest the proceeds? Round your answer to two decimal places.
