lnx=4. how do i do this problem...
e^lnx = x
e^4 = use calculator
x = e^4
thanks!
To solve the equation lnx = 4, you need to use the properties of logarithms. Here's how you can do it step by step:
Step 1: Start with the equation lnx = 4.
Step 2: Convert the logarithmic equation into an exponential equation by using the property that ln(e^x) = x. Rewrite the equation as e^4 = x.
Step 3: Evaluate e^4 using a calculator or using the approximation e ≈ 2.71828. The value of e^4 is approximately 54.5982.
Step 4: Substitute the value of e^4 back into the equation x = e^4 to find the solution. Therefore, x ≈ 54.5982.
So, the solution to the equation lnx = 4 is x ≈ 54.5982.
