Textbook Question
Solve each equation.
48=6e4k

1
Start by isolating the exponential term. Divide both sides of the equation by 6 to get: \( e^{4k} = \frac{48}{6} \).
Simplify the right side of the equation: \( e^{4k} = 8 \).
To solve for \( k \), take the natural logarithm of both sides: \( \ln(e^{4k}) = \ln(8) \).
Use the property of logarithms that \( \ln(e^x) = x \) to simplify the left side: \( 4k = \ln(8) \).
Finally, solve for \( k \) by dividing both sides by 4: \( k = \frac{\ln(8)}{4} \).
