Find the missing x or b
\n" ); document.write( ":
\n" ); document.write( "a. log(2)x=2
\n" ); document.write( "write the exponent equiv of logs
\n" ); document.write( "x = 2^2
\n" ); document.write( "x = 4
\n" ); document.write( "so we have
\n" ); document.write( "log2[4] = 2
\n" ); document.write( ":
\n" ); document.write( "b. log(b)4=2/3
\n" ); document.write( "write the exponent equiv of logs
\n" ); document.write( " $\"b%5E%282%2F3%29\"$ = 4
\n" ); document.write( "Cube both sides
\n" ); document.write( " $\"b%5E2\"$ = $\"4%5E3\"$
\n" ); document.write( " $\"b%5E2\"$ = 64
\n" ); document.write( "b = $\"sqrt%2864%29\"$
\n" ); document.write( "b = 8
\n" ); document.write( "so we have
\n" ); document.write( "log8[4] = $\"2%2F3\"$ \n" ); document.write( "

\n" );
