You can put this solution on YOUR website!
Such a numberis irrational which means its decimal form is a non-repeating
\n" ); document.write( "pattern.
\n" ); document.write( "You can never write the entire decimal form but you can carry it out
\n" ); document.write( "to as many places as you have the patience to do so.
\n" ); document.write( "---------
\n" ); document.write( "For example:
\n" ); document.write( "sqrt 80 = ?
\n" ); document.write( "8\n" ); document.write( "8.9\n" ); document.write( "8.94\n" ); document.write( "8.944\n" ); document.write( "8.9442\n" ); document.write( "----------
\n" ); document.write( "If you square 8.9442 you will find it is less than 80
\n" ); document.write( "If you square 9 you will find it is more than 80.
\n" ); document.write( "So the square root is in between 8.9442 and 9.
\n" ); document.write( "You can keep this up forever if you wish.
