Solve for x:
\n" ); document.write( "\"Log%5B2%5D%28x%29+=+2\" Rewrite in exponential form. If \"Log%5Bb%5D%28x%29+=+y\", then \"b%5Ey+=+x\" so...
\n" ); document.write( "\"2%5E2+=+x\"
\n" ); document.write( "\"x+=+4\"
\n" ); document.write( "Solve for b:
\n" ); document.write( "\"Log%5Bb%5D%284%29+=+2%2F3\" Rewrite in exponential form:
\n" ); document.write( "\"b%5E%282%2F3%29+=+4\" Raise both sides to the \"3%2F2\" power.
\n" ); document.write( "\"%28b%5E%282%2F3%29%29%5E%283%2F2%29+=+4%5E%283%2F2%29\" Simplify.
\n" ); document.write( "\"b+=+sqrt%284%5E3%29\"
\n" ); document.write( "\"b+=+sqrt%2864%29\"
\n" ); document.write( "\"b+=+8\"
\n" ); document.write( "
