## Enter natural log statement

Evaluate the following logarithmic expression

0.96^d=0.13333333333

##### Take the natural log of both sides

Ln(0.96d) = Ln(0.13333333333)

##### Use a logarithmic identity

Ln(an) = n * Ln(a)

Using that identity, we have
n = d and a = 0.96, so our equation becomes:

dLn(0.96) = -2.0149030205673

-0.040821994520255d = -2.0149030205673

##### Divide each side of the equation by -0.040821994520255

 -0.040821994520255d -0.040821994520255
 =
 -2.0149 -0.040822

d = 49.358269830924

d = 49.358269830924
