Luba_88 [7]

Answer:

$\frac{144}{25}$

Step-by-step explanation:

We begin with $(-2 \frac{2}{5} )^2$

First, lets turn this mixed number into an improper fraction/

$-2 \frac{2}{5} =-\frac{12}{5}$

Now that we have this, we can square it and then simplify it.

$(-\frac{12}{5} )^2 =\frac{12^2}{5^2} *(-1)^2=\frac{144}{25} *1=\frac{144}{25}$
