I assume the task is to simplify.
![(5x^2)^2 = 5^2 (x^2)^2 = 25 x^4](https://tex.z-dn.net/?f=%20%285x%5E2%29%5E2%20%3D%205%5E2%20%28x%5E2%29%5E2%20%3D%2025%20x%5E4%20)
Answer: ![25x^4](https://tex.z-dn.net/?f=%2025x%5E4)
The answer to your question is c
Answer:
0.5
Step-by-step explanation:
If the 30 is in degrees, then the answer is 1/2 or 0.5. If the 30 is in radians, then your answer is -1.0.

![12\pi \: {cm}^{2}](https://tex.z-dn.net/?f=12%5Cpi%20%5C%3A%20%20%7Bcm%7D%5E%7B2%7D%20)
EXPLANATION
We want to find the area of the shaded region.
We find the area of the smaller circle and subtract from the area of the larger circle.
Area of smaller circle is
![a = \pi \: \times 2^{2} = 4\pi](https://tex.z-dn.net/?f=a%20%3D%20%5Cpi%20%5C%3A%20%5Ctimes%20%20%202%5E%7B2%7D%20%20%3D%204%5Cpi)
Area of larger circle is
![A = \pi \: \times {4}^{2} = 16\pi](https://tex.z-dn.net/?f=A%20%3D%20%5Cpi%20%5C%3A%20%20%20%5Ctimes%20%7B4%7D%5E%7B2%7D%20%20%3D%2016%5Cpi)
The area of the shaded region is:
![16\pi - 4\pi = 12\pi](https://tex.z-dn.net/?f=16%5Cpi%20-%204%5Cpi%20%3D%2012%5Cpi)
