Question 978807
Given
{{{log(a,(7)) = 1.946}}}
{{{log(a,(5)) = 1.609}}}
-------------------------------------------------------
What we want to find 
{{{log(a,(7/5))}}}
-------------------------------------------------------
Use <a href="http://www.purplemath.com/modules/logrules.htm">rule 2</a>(of the log rules shown on that page) to get


{{{log(a,(7/5)) = log(a,(7))-log(a,(5))}}}


{{{log(a,(7/5)) = 1.946-1.609}}}


{{{log(a,(7/5)) = 0.337}}}
