Answer 2

Happy to help Mylie.

We use the basic idea that

$a^{-n}=\dfrac{1}{a^n}$

7³ 16⁻⁹ = 7³ / 16⁹

Let's number the choices left to right first row 1-4, second 5-8, last 9-12

Answer: Choice 12

8⁻⁶ / 21⁻⁴ = 21⁴ / 8⁶

When the negative exponent is in the denominator it becomes a positive exponent in the numerator.

Answer: Choice 5

(7/16)⁻³ = (16/7)³ = 16³/7³

Answer: Choice 3

16³ (-7)⁻³ =   16³ / (-7)³

We could simplify more but this is

Answer: Choice 7

((8)(21))⁻⁴ =  1 / ((8)(21))⁴

Answer: Choice 1

8(21⁻³) = 8/21³

Answer: Choice 10

11⁻⁷ 5⁹ / 6⁹ = 5⁹ / (11⁷ 6⁹)

Answer: Choice 11

I think I'll leave the last three for you.
