SUMMARY

The discussion centers on solving the equation e^x = 2. The user correctly applies logarithmic properties by taking the natural logarithm (ln) of both sides, resulting in x = ln(2). The user further simplifies this to x = ln(ln(2)), which is confirmed as a valid approach. The solution is verified using Symbolab, highlighting the importance of simplification in logarithmic equations.

I just wanted to double check that I was doing this right ( if the math in my process makes sense).

Question: Solve for x given the following equation.

eex= 2

I found the ln of both sides, so :

ex= ln2

and then found ln again

x= ln(ln(2))

Was this the correct way of doing this? I was checking my answer using symbolab and there was an extra step with simplifying in order to reach the same answer as mine, so I'm just double checking to see if this is alright.
