Answer:
9
Step-by-step explanation:
We want to evaluate
[tex]A^2[/tex]
for A=-3.
This means, we need to substitute A=-2, into the given equation and simplify.
We substitute to get:
[tex] A^2 = {( - 3)}^{2} [/tex]
In this case the base is -3, so it multiplies itself twice.
[tex]A^2 = {( - 3)} \times - 3[/tex]
This gives us:
[tex]A^2 = 9[/tex]
