Answer:

19) ( $\frac{-2}{5}$ )^2 = $\frac{4}{25}$

20) - $9^{2}$ = -81

21) $2^{4}$ = 16

Step-by-step explanation:

The only wrong ones are

19) ( $\frac{-2}{5}$ )^2 = $\frac{4}{25}$

20) - $9^{2}$ = -81 ... negative is not inside a parenthesis that's why it is still negative

21) you can add another way is $2^{4}$ = 16

Everything else looks good. Great job!
