Correct. Apply algebra to your problem, as you did:
\n" ); document.write( "w = 8d^2 divide both sides by 8:
\n" ); document.write( "w/8 = d^2 take the square root, both sides:
\n" ); document.write( "√w/8 = d
\n" ); document.write( "or
\n" ); document.write( "d = √w/8
\n" ); document.write( "
\n" ); document.write( "
\n" );
