Remember that if something is raised to a fraction exponent, the denominator of the fraction is the radical and the numerator stays a power. So it becomes:
fourth root of (48c)^3

Answer:
The rangers
Step-by-step explanation:
Their number of wins didn't go up. In fact their wins decreased the most.
 
        
                    
             
        
        
        
Let x = sue
and then let 3x-84 = marcia
therefore
(x)+(3x-84)=132
4x-84=132
4x=216
x=54
however just solving for x doesnt completely solve. it only shows sues money because x = sue
for marcia
3x-84
3(54)-84
162-84
78
therefore Marcia has 78$.
        
             
        
        
        
Answer:
cos2t/cos²t 
Step-by-step explanation:
Here the given trigonometric expression to us is ,
 
 
We can write the numerator as , 
 
 
Recall the identity ,
 
 
Using this we have ,
 
 
Again , as we know that ,
 
 
Therefore we can rewrite it as ,
 
 
Again using the first identity mentioned above ,
 
 
Or else we can also write it using ,
 
 
Therefore ,
  
 
And we are done !

We can rewrite cos 2x as , 
 
 
As we know that ,
 
 
So that ,
 
 
On simplifying,
 
 
Hence,
