Answer:
64z^2
Step-by-step explanation:
Here's why, it's actually very simple we use exponent rule when raising something to a power. In this case we're raising the term to the second power. So we raise both -8, and z. As so: (-8)^2 x (z)^2
Which equals 64z^2.

which agrees with the first answer listed among your options
Step-by-step explanation:
Volume of cone: 
So in our case:
1) Base s a circle, of radius "x" then the surface of this is: 
2) the cone's height is "2x"
Therefore the cone's volume is: 
Since, you're moving up in exponents, you will move right the number of decimal spaces equivalent to the power of the exponent. Hence, move the decimal point five spaces to the right. There, you now have your answer. :)
