Answer:
Option B is correct
[tex]\ln 70.81 =a[/tex]
Step-by-step explanation:
Using the logarithmic rule:
[tex]\ln e^x = x[/tex]
Given the exponential equation:
[tex]70.81=e^a[/tex]
Taking log with base e (i.e ln) both sides, we have;
[tex]\ln 70.81 = \ln e^a[/tex]
Apply the rule we have;
[tex]\ln 70.81 =a[/tex]
Therefore, [tex]\ln 70.81 =a[/tex] logarithmic equation is equivalent to the given exponential equation
