  1. Oct 3, 2005 #1
    [tex]1 = a^{b}[/tex]

    How can I isolate b in that equation?

    Thanks. ^^

    That's the whole point of logarithms. logax= y if and only if ay= x.

    An algebraic property of logarithms may also be useful here. If you cannot find them in your text, here is an online http://people.hofstra.edu/faculty/Stefan_Waner/RealWorld/calctopic1/logs.html [Broken]. Pay particular attention to the table of identities.
