Answer:
![\[x^{\frac{1}{4}}\]](https://tex.z-dn.net/?f=%5C%5Bx%5E%7B%5Cfrac%7B1%7D%7B4%7D%7D%5C%5D)
Step-by-step explanation:
x is a variable which has been declared of type double.
Then square root of x can be expressed as ![\[\sqrt{x}\]](https://tex.z-dn.net/?f=%5C%5B%5Csqrt%7Bx%7D%5C%5D)
The quartic root of a number is the square root of its square root.
In other words, quartic root of x can be expressed as ![\[\sqrt{\sqrt{x}}\]](https://tex.z-dn.net/?f=%5C%5B%5Csqrt%7B%5Csqrt%7Bx%7D%7D%5C%5D)
This can be expressed equivalently as ![\[\sqrt{x^{\frac{1}{2}}}\]](https://tex.z-dn.net/?f=%5C%5B%5Csqrt%7Bx%5E%7B%5Cfrac%7B1%7D%7B2%7D%7D%7D%5C%5D)
![\[={x^{\frac{1}{4}}}\]](https://tex.z-dn.net/?f=%5C%5B%3D%7Bx%5E%7B%5Cfrac%7B1%7D%7B4%7D%7D%7D%5C%5D)

The total number of hoagies sold is equal to the sum of Italian hoagies and roast beef hoagies. So,
42 + 53 = 95
Thus, the ratio is 42 : 95
I think 24. C and 25. A I think not sure think
