How would you explain square roots: a number that is multiplied twice.
\n" ); document.write( "For example: the square root of 9 is 3 because 3x3=9. Three is the number that is multiplied twice to equal 9.\r
\n" ); document.write( "\n" ); document.write( ".
\n" ); document.write( "cube roots: a number that is multiplied three times. For example:
\n" ); document.write( "The third root of 27 is 3 because 3x3x3=27. The number (3) is multiplipied three times to equal 27.
\n" ); document.write( "Another example: the third root of 64 is 4 because 4 is multiplied three times to equal 64 (4x4x4=64) \r
\n" ); document.write( "\n" ); document.write( ".
\n" ); document.write( "nth roots: a number that is multiplied nth number of times to equal the radicand (the number underneath the radical sign).
\n" ); document.write( ".
\n" ); document.write( "What are some limitations of square root? the radicand must always be equal to or greater than zero (a positive number). Because squaring any number will result in a positive number. For example:
\n" ); document.write( "(-2)(-2)=4
\n" ); document.write( "and (+2)+2)=4 also.
\n" ); document.write( "Therefore the square root of 4 is +2 or -2.
\n" ); document.write( " \n" ); document.write( "

\n" );
