Answer:

[tex]x = \frac{ln(k)}{5}[/tex]

Explanation:

Given

[tex]e^{5x} = k[/tex]

Required

Solve for x

[tex]e^{5x} = k[/tex]

Take natural logarithm of both sides:

[tex]ln(e^{5x}) = ln(k)[/tex]

Apply law of logarithm:

[tex]ln(e^{f(x)}) = f(x)[/tex]

So, we have:

[tex]ln(e^{5x}) = ln(k)[/tex]

[tex]5x = ln(k)[/tex]

Divide through by 5

[tex]x = \frac{ln(k)}{5}[/tex]
