I'm not sure what you mean by 3 or 6a^9, since there are only variables in the photo, but we can try breaking it down. 
Let's start with the bottom,
a^2 * a^3 would be a^5 because for exponents you add the exponents of what's multiplied (product rule)
Then using the quotient rule, where you subtract the exponents, a^5/a^5 = a^(5-5)
And anything to the 0th power is 1, so your answer should be 1
Hope that helps!
 
        
             
        
        
        
The perimeter of the square is 48
There are 4 equal-length sides to the square, making each side 12 in. in length
to find the area, multiply two sides of the perimeter
12 x 12 = 144
Perimeter: 48
Side: 12
Area: 144
hope this helps
        
             
        
        
        
Answer: 25 units squared
