Answer:
C
Explanation:
when you multiply numbers with exponents then you add the exponents and multiply the first digit
if you want an example or prove it replace the variables with a number 2 for a and 3 for b
(10(2)^5*(3)^3) * (5(2)^6*(3)^2)= 24883200
and c is equal to 24883200
you can try the same process for the rest to double check
