Question 742655
 1. Write x in terms of a , b and c
a) ln x = ln a + ln b - ln c
Follow the rules of logs we have
{{{ln(x) = ln((ab)/c)}}}
which is just:
x = {{{(ab)/c}}}
:
b) ln x = 2 ln a + 3 ln b - 1/2 ln c
rewrite using exponents
{{{ln(x) = ln(a^2) + ln(b^3) - ln(c^(1/2))}}}
we can write c as a square root:
{{{ln(x) = ln(a^2) + ln(b^3) - ln(sqrt(c))}}}
then
{{{ln(x) = ln((a^2b^3)/sqrt(c))}}}
which is
{{{x = ((a^2b^3)/sqrt(c))}}}
