Answer:
![\sqrt[7]{x^9}](https://tex.z-dn.net/?f=%5Csqrt%5B7%5D%7Bx%5E9%7D)
Step-by-step explanation:
its kinda difficult for me to explain so i guess just use this equation next time:
![x^{m/n} = \sqrt[n]{x^m}](https://tex.z-dn.net/?f=x%5E%7Bm%2Fn%7D%20%3D%20%5Csqrt%5Bn%5D%7Bx%5Em%7D)
I say B, I had to google it to make sure, but there are 3 phases in interphase. Interphase occurs before mitosis. The third phase in interphase is the DNA being copied.
