(-1/2)(2^1/2)=-(2^1/2)/2=-1/(2^1/2)
(-1/2)(2^1/2)=-(2^1/2)/2=-1/(2^1/2)

change it to (-5/2) and then (-5/2)(-5/2) and you get (25/4)
Unless you mean [-2(1/2)]
because 2 and 1/2 cancel each other out, then its (-1)(-1) and you get 1
Unless you mean [-2(1/2)]
because 2 and 1/2 cancel each other out, then its (-1)(-1) and you get 1
