5 0

Answer:

\frac{1}{9}

Step-by-step explanation:

Anything to the negative power becomes a fraction

So here we have (-3)⁻² which then becomes \frac{1}{(-3)^{2} }

This then simplifies to \frac{1}{9}

Not really 100% sure how to answer this, but if you would like to find the price of any item 10% off, you would just multiply the price by 0.9

EX: item cost $100

$100 x 0.9 = $90

Meaning the price of the item after the discount is applied would be $90
