\n" ); document.write( "As seen, you don't need a calculator to do this simplification, and you certainly don't have to apply change of base.
\n" ); document.write( "Some people don't even know what change of base is. Chances are, you don't either, but even if you do, you don't need to apply that here. \n" ); document.write( "
