Answer:
  is 200 times larger than
  is 200 times larger than  
Step-by-step explanation:
 
To compare both values we divide the exponents

6 divide by 3 is 2
for simplify exponents we use exponential property
a^m / a^n = a^(m-n)

364.5 because 9 to the third power is 729. 729 divided by 2 is 364.5
        
                    
             
        
        
        
Answer: 792
Step-by-step explanation:
From what I got it should be 792 because it is asking for doubles, triples, and home runs all together at the same amount that he got on his first year.
It says after 12 years
 Doubles 47 times 12 years = 564
Triples 4 times 12 years = 48
and 
Home runs 15 times 12 years = 180
564 + 48 = 612
612 + 180 = 792
