Question Solve lnc=15\ln c = 15 and write the exact solution set. Also provide approximate solutions to 4 decimal places.

Studdy Solution

STEP 1

Assumptions1. The given equation is lnc=15\ln c =15 . We are solving for cc
3. We are asked to provide both the exact solution and an approximate solution to4 decimal places

STEP 2

To solve for cc, we need to get rid of the natural logarithm on the left side of the equation. We can do this by applying the property of logarithms that states elna=ae^{\ln a} = a.So, we take the exponential of both sides of the equation.
elnc=e15e^{\ln c} = e^{15}

STEP 3

implify the left side of the equation using the property of logarithms mentioned above.
c=e15c = e^{15}This is the exact solution.

STEP 4

Now, to find the approximate solution to4 decimal places, we need to calculate the value of e15e^{15}.

STEP 5

Calculate the value of e15e^{15} to4 decimal places.
ce153269017.3725c \approx e^{15} \approx3269017.3725So, the solution set is c=e15c = e^{15} or approximated to4 decimal places is c3269017.3725c \approx3269017.3725.
