Hi dear!
\n" ); document.write( "Take the squares of numbers from 32 to 99.
\n" ); document.write( "i.e from
\n" ); document.write( "
\n" ); document.write( " $\"32%5E%282%29+to+99%5E%282%29\"$ ,On doing this,you will notice that they are made of 4 digit numbers and on taking the square root of those number,it will give a whole number.
\n" ); document.write( "Example; $\"32%5E%282%29=1024\"$
\n" ); document.write( "which is a 4 digit number and
\n" ); document.write( " $\"sqrt%281024%29=32\"$ which is a whole number.
\n" ); document.write( "Therefore,1024 being a 4 digit number is a perfect square.
\n" ); document.write( "Do thesame as the example above from numbers within 32 to 99.
