Step-by-step explanation:
The total amount of any purchase is computed as the sum of products of quantity and price.
_____
In some instances is is helpful to keep the units (dollars) with the numbers they apply to. Most times, the units will be left off, and you're expected to make sure they work out properly some other way.
Answer:
Step-by-step explanation:
Since this is a test/hw, I'll give a hint.
This problem at first can seem a bit difficult with q's and power's everywhere.
But let's take a step backward. A power is when your mutiplying something by itself again and again.
Ex: 3^3=3 times 3 times 3
But what if we had something liiiike this:
(3^3)2
In this case its now
(3 times 3 times 3)^2, so its "techinicaly" (27)^2. And you would a fairly large number, which I'm to lazy to solve. But that's not the point.
We've seen what a power is deconstructed, and what a power is. Because my explantion probably confused you more than it helped, I'll give an example.
(2^2)^2=(2 times 2)^2=(4^2=16=2^4
However, there is a shorter way to solve it.
(2^2)^2=2^(2 times 2)=2^4
Hope this helps.
