Question 61874
<pre><font size = 5><b>                              ln(5) + 2·ln(x) - 3·ln(z)

Use this rule of logarithms:

<i>A·ln(B) = ln(B<sup>A</sup>)</i>

to rewrite the 2nd and third terms:

                              ln(5) + ln(x<sup>2</sup>) - ln(z<sup>3</sup>)

Use this rule of logarithms:

<i>ln(AB) = ln(A) + ln(B)</i>

to rewrite the first two terms:

                                   ln(5x<sup>2</sup>) - ln(z<sup>3</sup>)

Use the rule of logarithms:

<i>ln(A/B) = ln(A) - ln(B)</i>

to rewrite this as

                                       ln(5x<sup>2</sup>/z<sup>3</sup>)
