-$\mathrm { e } ^ { ( \mathrm { x } + 3 ) } = 7$
A) $\mathrm { e } ^ { 21 }$
B) $\ln 7 - 3$
C) $\ln 10$
D) $\mathrm { e } ^ { 7 } + 3$

Quizplus · Accepted Answer

To solve the equation $e^{(x+3)} = 7$, take the natural logarithm (ln) of both sides to get $x + 3 = \ln 7$. Then, solve for $x$ by subtracting 3 from both sides, which gives $x = \ln 7 - 3$.

Solve the Equation e(x+3)=7\mathrm { e } ^ { ( \mathrm { x } + 3 ) } = 7e(x+3)=7

Solve the Equation $\mathrm { e } ^ { ( \mathrm { x } + 3 ) } = 7$
