In a 38.47 O B loga 38.47-3.65 OC.l0938.47 3.65e 0 D. In 38.47-a

Solution

e^a = 38.47

The opposite of exponential is neperian logarism (ln) so we can discart option b and c. We have now a and d. Let\'s solve the equation:

e^a = 38.47   applying ln to both sides:

ln (e^a) = ln 38.47

a = ln 38.47

Correct option is d. Hope this helps
