Use universal instantiation or universal modus ponens to fill in a valid conclusion for the argument. V real numbers r, a, and b, if r is positive, then (ryb - pab r= 3, a = 1/2, and b = 6 are particular real numbers such that r is positive. O (3(1/2),6 - 3((1/2)(6)) O ((-3)1/2)-6 - (-3)(1/2)(-6) O (3(1/2)6 - 3((1/2)(6)) O (1/2))6 = (1³)(2°) ((-3)1/2)6 = (-3)(1/2)(6)
