log 4 (x ^2 -3) + log 4 10=1
\n" ); document.write( "log 4 10(x ^2 -3) =1
\n" ); document.write( "10(x ^2 -3) = 4^1
\n" ); document.write( "10x^2 -30 = 4
\n" ); document.write( "10x^2 = 34
\n" ); document.write( "x^2 = 3.4
\n" ); document.write( "x = sqrt(3.4)
\n" ); document.write( "x = {-1.84, 1.84}
\n" ); document.write( "throw out the negative solution (extraneous) leaving:
\n" ); document.write( "x = 1.84\r
\n" ); document.write( "\n" ); document.write( "
