Question 102010: Let me try this again, I accidentally hit "Enter" before I got the problem typed in.
Ok, Now I am drowning in confusion and frustration. I am not even sure how to type this prblem in here, so I am going to have to describe the symbol and I will Place the Letter "V" were the symbol goes. I believe the symbol is called a "Radican" or something like that: it looks like a square root and division symbol combined.
SIMPLIFY BY RATIONALIZING THE DENOMINATOR???
(V11 - V5)
-----------
(V11 + V5)

My Advanced Greatfulness and Appreciation to the solver and clarifier of how to solve. Thank You!

Rationalizing the denominator works as such

Therefore
+%28sqrt%2811%29+-+sqrt%285%29%29+%2F+%28sqrt%2811%29+%2B+sqrt%285%29%29+

+%28sqrt%2811%29+-+sqrt%285%29%29%5E2+%2F+%2811+-+5%29+
Since +%28a+-+b%29%5E2+=+a%5E2+-+2%2Aa%2Ab+%2B+b%5E2+, so
+%2811+-+2%2Asqrt%2855%29+%2B+5%29+%2F+%2811+-+5%29+
+%2816+-+2%2Asqrt%2855%29%29+%2F+6+
+%282%2A%288+-+sqrt%2855%29%29%29+%2F+6+
+%288+-+sqrt%2855%29%29+%2F+3+
Hope that helps.
