√5 = 5^(1/2) 
Multiplying two number with the same base has as result a number with the same base and the sum of the exponents so:
1/2 + 3 = 7/2 
which means 
5^3 x 5^(1/2) = 5^(7/2)
        
             
        
        
        
If functions transfer some a to b via some formula, then inverse of such functions transfer b to a via some other formula.
Hope this helps.
 
        
                    
             
        
        
        
Answer:
C
Explanation: 
On the scatter plot, there is a dot where the lines for 6 and 3 meet. when looking for the ordered pair you would go along first then up (> then ^) so it would be (6,3). Another example, for the third dot on the plot, if you go along first you get 12 then when you go up you get 9 so the ordered pair for that would be (12,9). I really hope you understand what i mean and this helps as i struggled with explaining haha!
