Using the change of base formula: $\"Log%5Bb%5D%28M%29+=+Log%5Ba%5D%28M%29%2FLog%5Ba%5D%28b%29\"$ and in this problem, b(the old base) = 7, a = 10(the new base), M = 100.
\n" ); document.write( " $\"Log%5B7%5D%28100%29+=+Log%5B10%5D%28100%29%2FLog%5B10%5D%287%29\"$
\n" ); document.write( " $\"Log%5B7%5D%28100%29+=+2%2F0.8451\"$
\n" ); document.write( " $\"highlight%28Log%5B7%5D%28100%29+=+2.3666%29\"$ Rounded to the nearest ten thousandth. \n" ); document.write( "
