Answer:
6
Step-by-step explanation:
m = 3
n = 1
Equation 
m(m - n)     Substitute the givens
Solution
3(3 -1 )        Evaluate what is inside the brackets. 
3(2)      multiply
6
 
        
             
        
        
        
Answer:
6 1/5 = 31/5 and 2 3/4 = 11/4 as improper fractions, hope this helps!

(sqrt7)^6x = 49x - 6
There is no easy way to solve this . Drawing a graph will give a good approximation.
Draw  y = (sqrt7)66x
and y = 49x - 6     and see where they intersect
Ill draw it on desmos graphing tool and give you the link.
