Evaluate:
\n" ); document.write( " $\"Log%5B5%5D%281%2F5%29\"$
\n" ); document.write( " $\"Log%5B5%5D%281%2F5%29+=+x\"$ Rewrite this in exponential form:
\n" ); document.write( " $\"5%5Ex+=+1%2F5\"$ Rewrite the right side as an exponent:
\n" ); document.write( " $\"5%5Ex+=+5%5E%28-1%29\"$ Apply the identity: $\"If+a%5En+=+a%5Em\"$ then $\"n+=+m\"$
\n" ); document.write( " $\"x+=+-1\"$
\n" ); document.write( " \n" ); document.write( "

\n" );
