Rationalize the denominator. Assume that all expressions under radicals represent positive numbers.
\n" ); document.write( "a√-√b over √a+√b
\n" ); document.write( "I assume you meant to write it this way:
\n" ); document.write( "√a-√b over √a+√b
\n" ); document.write( "=(√a-√b)/(√a+√b)
\n" ); document.write( "multiply top and bottom by (√a-√b) (conjugate of (√a+√b))
\n" ); document.write( "=(√a-√b)^2/ (√a-√b)*(√a+√b)
\n" ); document.write( "=(√a-√b)^2/ (a-b)
\n" ); document.write( "
\n" );
