Question
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 (rºjb = rab
r= 3, a = 1/2, and b = 6 are particular real numbers such that r is positive.
(3(1/2),6 = 3((1/2)(6))
(-3)1/2)-6 = (-3)(1/2)(-6)
(3(1/2)j6 = 3((1/2)(6)»
O (1/2)³)6 = (1³)(2®)
O ((-3)1/2)6 = (-3)(1/2)(6)
