Answer: 2
Justitification:
1) Property:
![a^{(1/b)} = \sqrt[b]{a}](https://tex.z-dn.net/?f=a%5E%7B%281%2Fb%29%7D%20%3D%20%20%5Csqrt%5Bb%5D%7Ba%7D%20)
Therefore:
![16^{1/4}= \sqrt[4]{16}](https://tex.z-dn.net/?f=16%5E%7B1%2F4%7D%3D%20%20%5Csqrt%5B4%5D%7B16%7D%20)
2) 16 = 2⁴
3) Property
![\sqrt[n]{a^n} =a^{n/n}=a](https://tex.z-dn.net/?f=%20%5Csqrt%5Bn%5D%7Ba%5En%7D%20%3Da%5E%7Bn%2Fn%7D%3Da)
Therefore:
![\sqrt[4]{2^4} =2^{4/4}=2](https://tex.z-dn.net/?f=%20%5Csqrt%5B4%5D%7B2%5E4%7D%20%3D2%5E%7B4%2F4%7D%3D2)
Justitification:
1) Property:
Therefore:
2) 16 = 2⁴
3) Property
Therefore:
Answer:
Explanation:
Hello,
In this case, we employ the combined ideal gas law in order to understand the volume-gas-pressure behavior as shown below:
Hence, solving for the final pressure P2, we obtain (do not forget temperature must be absolute):
Best regards.
