Explanation:
Negative exponents tells us that the number has to be in the numerator (if it's in the numerator it has to be in the denominator):
![\frac{1}{4^{-4}}=4^4](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%5E%7B-4%7D%7D%3D4%5E4)
Now we just have to solve:
![4^4=4\times4\times4\times4=256](https://tex.z-dn.net/?f=4%5E4%3D4%5Ctimes4%5Ctimes4%5Ctimes4%3D256)
Answer:
The result is 256
Answer:
We have the expression -1(2x + 3) - 2(x - 1).
Distribute the -1 across the 2x and 3.
-1(2x + 3) - 2(x - 1) = -2x - 3 - 2(x - 1)
Now distribute the 2 across the x and -1.
-2x - 3 - 2(x - 1) = -2x - 3 - 2x + 2
Combine like terms.
-2x - 3 - 2x + 2 = -4x - 1
So, D -4x - 1 is the answer.
Answer:
![V=384\pi \ \text{unit}^3](https://tex.z-dn.net/?f=V%3D384%5Cpi%20%5C%20%5Ctext%7Bunit%7D%5E3)
Step-by-step explanation:
The attached figure shows a cylinder of radius 8 units and height 6 units. We need to find the volume of the cylinder. The formula is as follows :
![V=\pi r^2h\\\\V=\pi (8)^2\times 6\\\\V=384\pi](https://tex.z-dn.net/?f=V%3D%5Cpi%20r%5E2h%5C%5C%5C%5CV%3D%5Cpi%20%288%29%5E2%5Ctimes%206%5C%5C%5C%5CV%3D384%5Cpi)
So, the required volume of the cylinder is
