You can put this solution on YOUR website!
A radical expression is an expression containing a square root.
\n" ); document.write( "You would use a radical expression in a problem to find the root of a number.
\n" ); document.write( "For example:
\n" ); document.write( "The square root of 9 is 3 because 3*3=9 or 3^2=9
\n" ); document.write( "The square root of 4 is 2 because 2*2=4 or 2^2=4
\n" ); document.write( "The square root of 54 is the square root of 9*6. Now, since the 9 has a perfect square which is 3*3 you would take the square root of nine and your answer would be 3 square root of 6
\n" ); document.write( " $\"3sqrt%286%29\"$ \n" ); document.write( "

\n" );
