How can i find the ln of both sides of the equation?

6=6e^3x

and O.2= e^-kt

ln 6 = ln6 + 3x

which means x = 0

ln 0.2 = -1.609 = -kt
which means kt = 1.609

To find the natural logarithm of both sides of an equation, you can follow these steps:

Step 1: Start with the equation you're given:
6 = 6e^(3x)

Step 2: Take the natural logarithm (ln) of both sides of the equation. Remember that ln is the inverse function of e^x, so taking logarithm of both sides will isolate the exponent:
ln(6) = ln(6e^(3x))

Step 3: Use the properties of logarithms to simplify the equation. Specifically, you can use the rule ln(a * b) = ln(a) + ln(b):
ln(6) = ln(6) + ln(e^(3x))

Step 4: Since ln(e^x) = x, you can simplify further:
ln(6) = ln(6) + 3x

Now, let's move on to the second equation:

Given equation: 0.2 = e^(-kt)

To find the natural logarithm of both sides, follow these steps:

Step 1: Start with the equation you're given:
0.2 = e^(-kt)

Step 2: Take the natural logarithm (ln) of both sides of the equation:
ln(0.2) = ln(e^(-kt))

Step 3: Simplify using the property of logarithms:
ln(0.2) = -kt

These steps show you how to find the ln of both sides of the equations and simplify them.
