To solve the equation \( e^t = 984 \) algebraically, we'll follow these steps:
-
Take the natural logarithm of both sides: \[ \ln(e^t) = \ln(984) \]
-
Using the property of logarithms that states \( \ln(e^x) = x \), we simplify the left side: \[ t = \ln(984) \]
-
Now, we'll calculate \( \ln(984) \) using a calculator: \[ \ln(984) \approx 6.891 \]
Thus, the solution for \( t \) is approximately: \[ t \approx 6.891 \]
Checking Graphically:
To check this graphically, you can plot the function \( y = e^t \) and the line \( y = 984 \). The point of intersection will give you the solution for \( t \).
-
Plot the function \( y = e^t \), which is an exponential curve that starts at \( (0, 1) \) and increases rapidly as \( t \) increases.
-
Draw a horizontal line at \( y = 984 \).
-
The \( t \)-coordinate of the intersection point of the curve and the line represents the solution for \( t \).
If you perform this plot using graphing software or a graphing calculator, you should see that the point of intersection aligns with \( t \approx 6.891 \), confirming our algebraic solution.
Hence, the final answer is: \[ t \approx 6.891 \] (rounded to three decimal places).
