Question

Simplify the expression

Answer 1

729

To solve this, we need to start on the inside and work out; solving one part at a time.

[{(-1)^3 / (-3)^-3}]^2

1. (-1)^3 = -1

2. (-3)^-3 = - 1/27

3. (-1) / (- 1/27) = 27

4. 27^2 = 729

Answer 2

729

Explanation:

[(-1)^3]^2 /[(-3)^-3]^2

= 1 * [(-3)^3]^2

= 1 * 729

= 729
