Answer:

Step-by-step explanation:
We are given that 

Differentiate w.r.t x

By using formula 







Hence, the derivative of function

Answer:
-16
Step-by-step explanation:
So let’s solve for 7x. So 7x=34. So 7x-50 is 34-50 or -16
 
        
             
        
        
        
Using logarithms property of log(x)+log(y)=log(xy)
so here, you can sum the equation to;

so you can simply say that;

and by multiplying (x+6)*(x-6)

and as you know also that;

 is same as 

so you can simply state it as;

And you can check your work by substituting with 10 instead of x in the original function.
Hope this helps!
