A) $e ^ { 5 x }$
B) $\mathrm { e } ^ { 5 x } - \mathrm { e } ^ { - 5 \mathrm { x } }$
C) $\frac { e ^ { 5 x } } { 4 }$
D) $e ^ { x ^ { 5 } }$

Question

Quizplus · Accepted Answer

The expression $( \sinh x + \cosh x ) ^ { 5 }$ simplifies to $e^{5x}$ because $\sinh x + \cosh x = e^x$, and raising this to the fifth power gives $e^{5x}$.
