Answer:10
Step-by-step explanation:
28-4-4=20
20÷2=10
10+10+4+4=28
 
        
             
        
        
        
Answer:
   ![\displaystyle\frac{\sqrt[4]{3x^2}}{2y}](https://tex.z-dn.net/?f=%5Cdisplaystyle%5Cfrac%7B%5Csqrt%5B4%5D%7B3x%5E2%7D%7D%7B2y%7D)
Step-by-step explanation:
It can work well to identify 4th powers under the radical, then remove them.
   ![\displaystyle\sqrt[4]{\frac{24x^6y}{128x^4y^5}}=\sqrt[4]{\frac{3x^2}{16y^4}}=\sqrt[4]{\frac{3x^2}{(2y)^4}}\\\\=\frac{\sqrt[4]{3x^2}}{2y}](https://tex.z-dn.net/?f=%5Cdisplaystyle%5Csqrt%5B4%5D%7B%5Cfrac%7B24x%5E6y%7D%7B128x%5E4y%5E5%7D%7D%3D%5Csqrt%5B4%5D%7B%5Cfrac%7B3x%5E2%7D%7B16y%5E4%7D%7D%3D%5Csqrt%5B4%5D%7B%5Cfrac%7B3x%5E2%7D%7B%282y%29%5E4%7D%7D%5C%5C%5C%5C%3D%5Cfrac%7B%5Csqrt%5B4%5D%7B3x%5E2%7D%7D%7B2y%7D)

The applicable rules of exponents are ...
   1/a^b = a^-b
   (a^b)(a^c) = a^(b+c)
The x-factors simplify as ...
   x^6/x^4 = x^(6-4) = x^2
The y-factors simplify as ...
   y/y^5 = 1/y^(5-1) = 1/y^4
The constant factors simplify in the usual way:
   24/128 = (8·3)/(8·16) = 3/16
 
        
             
        
        
        
The probability of her winning a game would be 5/9 because if she loses 4/9 games then 5/9 games must be wins.
