You can put this solution on YOUR website!
x (4^2) = 7 / x\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "16 x^2 = 7\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x = ±√7 / 4\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "since logarithms are NOT defined for negative arguments ___ x = √7 / 4 \n" ); document.write( "
\n" );
