Suppose that ln 2 = a and in 3 = b. Use rules of logarithms to write each log in terms of a and b.
(1) ln (2/3)
(2) ln (4throot{(2/3)}
Since the pronumerals a and b are used in the question, your excellent advice might be misunderstood. Re-pronumeraling:
$\displaystyle \ln{(A \cdot B)} = \ln{A} + \ln{B}$
$\displaystyle \ln{\left(\frac{A}{B}\right)} = \ln{A} - \ln{B}$
$\displaystyle \ln{(A)^n} = n\ln{A}$
$\displaystyle \sqrt[n]{A} = A^{\frac{1}{n}}$
