-$( \sinh x + \cosh x ) ^ { 7 }$
A) $e ^ { x ^ { 7 } }$
B) $\mathrm { e } ^ { 7 \mathrm { x } }$
C) $\mathrm { e } ^ { 7 x } - \mathrm { e } ^ { - 7 \mathrm { x } }$
D) $\frac { e ^ { 7 x } } { 4 }$

Question

Quizplus · Accepted Answer

The expression $( \sinh x + \cosh x ) ^ { 7 }$ simplifies to $(e^x)^7$ because $\sinh x + \cosh x = e^x$. Therefore, the simplified result is $e^{7x}$.
