it a log problem?

e^x=87

yes. to find x, take log of both sides:

ln(e^x) = ln(87)
x = ln(87) = 4.466

Yes, the equation e^x = 87 is a logarithmic problem.

To find the solution, we can take the natural logarithm (ln) of both sides of the equation.

ln(e^x) = ln(87)

The natural logarithm of e^x simplifies to just x:

x = ln(87)

Using a scientific calculator or an online calculator with a natural logarithm function, you can evaluate ln(87) to find the value of x.
