Answer:
1 of 8: (729, 81, 9, 1)
2 of 8: 1 = (-1)^0 = 2^0
3 of 8: 1
Explanation:
The basic rule is that any non-zero value to the zero power is 1. It doesn't matter whether the value is positive or negative. Raising it to the zero power makes it 1.
So, for question 2 of 8, the two equivalent expressions can be anything raised to the zero power (or anything with a value of 1, for that matter).

In the order of the attachments, ...
3) 5^0 = 1
2) (-5.7)^0 = 1
two other expressions could be (-1)^0 and 2^0.
1) Each row of the table is the previous row divided by 9. Top-down, the missing table values are 729, 81, 9, 1. (Note that 9^0 = 1.)
