Final answer:
To solve the equation e^{e^x} = 15, take the natural logarithm of both sides of the equation and simplify to x = ln(15).
Step-by-step explanation:
To solve the equation e^{e^x} = 15, we can take the natural logarithm of both sides of the equation. This will cancel out the exponential function and leave us with ln(e^x) = ln(15). Using the property of logarithms that ln(e^x) = x, we can simplify the equation to x = ln(15).
So the correct answer is x = ln(15).
