if lnx=2 what does x equal? I think it has something to do with e^x but not sure exactly how to solve for x.
are you Riley?
if so, look back at your last post re this.
okay, yeah sorry I forgot to type my name in.
To solve for x when given lnx = 2, you are correct that you will need to use the exponential function e^x.
Here's how you can solve it step by step:
Step 1: Start with the equation lnx = 2.
Step 2: To isolate x, you need to eliminate the natural logarithm. To do so, raise both sides of the equation to the base e (exponential form), which is the inverse function of ln(x). This gives you e^(lnx) = e^2.
Step 3: Since e^(lnx) is equivalent to x, the equation simplifies to x = e^2.
Therefore, x equals e^2, which is approximately 7.389.
Note: The natural logarithm (ln) is the inverse function of the exponential function e^x. So when you raise e to a power (e^x), it cancels out the natural logarithm, giving you the original value of x.
