Answer:
Step-by-step explanation:
first the parenthesis
3^4/3^0=3^4
anything raised to the power of 0 is 1
(3^4)^2=3^8     you multiply the powers
3^-6 * 3^8= 3^(-6+8)=3^2
 
        
             
        
        
        
Answer:
25% decrease
Step-by-step explanation:
Percent change can be found by doing difference/original
(950,000 - 712,500) / 950,000
= 0.25
There was a 25% decrease in the population

The value of x is 
1. x= -37/48
2. x=0
3.  x = 33/4
4.  x= -20/7
<h3>What is equation?</h3>
A mathematical statement consisting of an equal symbol between two algebraic expressions that have the same value.
1.  6(8 x + 6) + = - 1
    48x + 36 = -1
   x= -37/48
2.  9x/7 + 6 = 6
 9x/7= 6-6
 9x/7 =0
x= 0*7/9
x= 0
3. 2x/11 (11 - 7) = 6
     x * 4= 6*11/2
     4x= 33
     x = 33/4
4. 11x/4 (4 - 2) = 9x + 10
  11x/4 * 2 = 9x +10
11/2*x = 9x +10
-7/2x = 10
 x= -20/7
