For this case we have that by definition of properties of powers and roots, it is fulfilled that:
![\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}](https://tex.z-dn.net/?f=%5Csqrt%20%5Bn%5D%20%7Ba%20%5E%20m%7D%20%3D%20a%20%5E%20%7B%5Cfrac%20%7Bm%7D%20%7Bn%7D%7D)
So:
![\sqrt [4] {9 ^ {\frac {1} {2} x}} = 9 ^ {\frac {\frac {1} {2}} {4} x} = 9 ^ {\frac {1} {8} x}](https://tex.z-dn.net/?f=%5Csqrt%20%5B4%5D%20%7B9%20%5E%20%7B%5Cfrac%20%7B1%7D%20%7B2%7D%20x%7D%7D%20%3D%209%20%5E%20%7B%5Cfrac%20%7B%5Cfrac%20%7B1%7D%20%7B2%7D%7D%20%7B4%7D%20x%7D%20%3D%209%20%5E%20%7B%5Cfrac%20%7B1%7D%20%7B8%7D%20x%7D)
So, we have to:
![\sqrt [4] {9 ^ {\frac {1} {2} x}} = 9 ^ {\frac {1} {8} x}](https://tex.z-dn.net/?f=%5Csqrt%20%5B4%5D%20%7B9%20%5E%20%7B%5Cfrac%20%7B1%7D%20%7B2%7D%20x%7D%7D%20%3D%209%20%5E%20%7B%5Cfrac%20%7B1%7D%20%7B8%7D%20x%7D)
Answer:

Option B
j^3
_______
4^2 h^4
when you have negatives, you want them to be positive. To do that you need to convert it into a fraction
Answer:
A and A- minus that is my best time
Answer:
It would be 55,200
Step-by-step explanation:
If she assumes her raise goes up by 5 % each year, her raise i n. 4 years will be 20%. So, 46,000x0.2= 9200. 9200+ 46,000 = 55,200.
