R2 • r • r 5 multiply or divide as indicated.

r^8

Step-by-step explanation:

r 2 • r • r 5

Assuming that r 2 means r^2

r ^2 • r • r^ 5

When the bases are the same and we are multiplying, we add the exponents

r ^2 • r^1 • r^ 5

r^(2+1+5)

r^(8)

Step-by-step explanation:

You need to remember a property called "Product of powers property". This property states the following:

You can observe that the bases of the expression are equal, then you can apply the property mentioned before.

Knowing this, you can make the multiplication indicated. Therefore, you get that the product is:

this is answer of 144 cubic meters
