What will be an ideal response?
The statement is false. The easiest way to simplify the expression is to multiply both the numerator and denominator by the conjugate of the denominator, 5 + 
. Since (a + b)(a - b) = a2 - b2, there will thus be no radical expression remaining in the denominator. (Explanations will vary.)
