Answer:
A.) 36
Step-by-step explanation:
For a perfect square trinomial, a = 1 b = 2x c = x². For an example, (x+3)² = x² + 6x + 9.
For this trinomial, divide "b" by 2 to get 6. Square this number and you will have 36.
x² + 12x + 36
3^(-4) means "one over 3^4"
1/(3^4)
That's equal to
1/81
and
(1/3)^4
This is also equal to 3^2/3^6.
So four of those are correct.
