Answer: 
Step-by-step explanation:
You need to remember the Product of powers property:

Then, knowing this property, now you have to apply the Distributive property. So:

Finally, to simplify this expression, you need to add the like terms.
Therefore, you get that the product is:

I think this is right.. I tried my best. If u get it sorry... I’m very sorry
1. Divide 7.20 by 4 since the 4 are the pencils
2.divide 7.20 by 5 ( 5 represents the erasers )
3. Then finally multiply 1.44 from 7.20/5 and
2 and u get 2.88
