I am assuming the V means square root
+x%5E2y%5E3+%2F+sqrt%28x%5E2+%2B+y%5E2%29+
x = 6
y = -8
Plug them in
+6%5E2%28-8%5E3%29+%2F+sqrt%286%5E2+%2B+-8%5E2%29+
work the exponents
+36%28-512%29%2F+sqrt%2836+%2B+64%29+
multiply and add
+18432%2F+sqrt%28100%29+
remeber a sqrt yeilds a + and a - answer
+18432%2F10+ and +18432%2F-10+
reduce
+1843.2+ and +-1843.2+
