I say the answer is 9 because he wrapped 8 games and 1 console and 8+1=9.
Answer: The simplified form is 
Step-by-step explanation:
Since we have given that

As we know the "Exponential law":

So, it becomes

Now, at last it becomes,

Hence, the simplified form is 
Arc length is the angle/360 times circumference. The diameter of the unit circle is 2. So the circumference of the unit circle is 2pi, if you use 3.14 for pi, then the circumference is 6.28. So your equation is
x/360 times 6.28=4.2, divide by 6.28, then multiply by 360
x=240.76432
Your answer rounded to the nearest thousanth is 240.764
An operation that is done to a value and it stays the same, it is called the "identity property".
Some quick examples:
Adding any number with zero will result in the same number.
Multiplying any number with one will result in the same number.
Hope this helps!
