What is the value of u?
(1) |u| + |v| = 0
since modulus is always >= 0 and it is given that sum of two modulus is 0 it implies that both u and v = 0
Sufficient.
(2) u^2 + v^2 = 0
Again, square of a number is always >=0. So from given information we can conclude that u and v are both equal to 0
sufficient
