Answer:
Step-by-step explanation:
you ate 3
you paid $9.45 for the 3
to find the cost of the whole pizza you need to know how much each slice costs so
9.45 / 3 = $3.15 a slice
so each slice is $3.15 and there are 8 slices and you need to know how much they cost altogether so
3.15 * 8 = $25.20

1). Step 4:
     
 
    ![x=\sqrt[3]{5^4}](https://tex.z-dn.net/?f=x%3D%5Csqrt%5B3%5D%7B5%5E4%7D) [Since,
 [Since, ![a^{\frac{1}{3}}=\sqrt[3]{a}](https://tex.z-dn.net/?f=a%5E%7B%5Cfrac%7B1%7D%7B3%7D%7D%3D%5Csqrt%5B3%5D%7Ba%7D) ]

2). He simplified the expression by removing exponents from the given expression.
3). Let the radical equation is,
    
    Step 1:
    
    Step 2:
    
    Step 3:
    
    Step 4:
    
4). By substituting  in the original equation.
 in the original equation.
    
                          
                          
There is no extraneous solution.
 
 
        
             
        
        
        
Well 2 to the second power would be 2 * 2 which equals 4
