Answer:
x= 2
Explanation:
1. Determine the defined range 
 2/5x = 0.08
2. Multiply both sides of the equation by 5 to the power of x
 2= 0.08 x 5x
3. Swap the sides of the equation 
0.08 = 5x = 2
4. Divide both sides by 0.08
5x = 25 
5. write the number in exponential form with the base of 5 
5x = 5 to the power of 2
6. Since the bases are the same, set the exponents equal 
x=2
