Ok let's do this*pops knuckles*
let's add the first side 

order of operations demands that we do multiplication first(P.E.M.D.A.S)
so 

now we can add the 1 from 

into our six

now we substract 

 now we have 

now we focus on the 
other side

since 5 is in paranthesis we use something called the distributive property. it mean we will multiply the 5 by both of the 2. 

now we have 

 (the three is from the original equation)
now we plug in our final numbers

or 

I hope this helps
 
        
                    
             
        
        
        
The area = 1/2 * base * height
202.5 = 1/2 *  base * 15
measure of the base =  202.5 / (1/2 * 15)
=   27 answer

Answer:
3 * n^(1/6)
Step-by-step explanation:
The square root can be written as ^ 1/2
The cube root can be written as ^ 1/3
So the sixth root can be written as ^ 1/6
3 * n^(1/6)
