Answer:
(A)
(D)
Step-by-step explanation:
We want to determine which of the expression is equivalent to:
![\sqrt[3]{128}^ x](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B128%7D%5E%20x)
By the law of indices:
![\sqrt[3]{128}=128^{1/3}\\$Therefore:\\\sqrt[3]{128}^ x \\=(128^{1/3})^x\\=128^{x/3}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B128%7D%3D128%5E%7B1%2F3%7D%5C%5C%24Therefore%3A%5C%5C%5Csqrt%5B3%5D%7B128%7D%5E%20x%20%5C%5C%3D%28128%5E%7B1%2F3%7D%29%5Ex%5C%5C%3D128%5E%7Bx%2F3%7D)
Similarly:
![\sqrt[3]{128}^ x \\=\sqrt[3]{64*2}^ x\\=(4\sqrt[3]{2})^ x\\=(4(2^{1/3}))^x](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B128%7D%5E%20x%20%5C%5C%3D%5Csqrt%5B3%5D%7B64%2A2%7D%5E%20x%5C%5C%3D%284%5Csqrt%5B3%5D%7B2%7D%29%5E%20x%5C%5C%3D%284%282%5E%7B1%2F3%7D%29%29%5Ex)
Answer:
m(BCD)=180°-m(BCA). In the triangle ABC m(BCA)=m(ABC)=(180-52)/2=64°. Finally, m(BCD)=180-64=116°
