Am i right?
#1, yes
#2, no, (anything)^0 = 1, except 0^0 which is undefined
#3, can't make out the question
if your problem was -1/(4^-4)
then -1(4^4) = -256 , not a given choice, all your choices contain a y
If you have a typo and you meant -1/y^-4
then -y^4
#1 ok
#2 nope. anything to the zero power is 1.
Think about it. x^2/x^2 = x^(2-2) = x^0
But of course, x^2/x^2 = 1
#3 no idea - garbled
Yes, -1 over y^–4 is what i meant.
