Answer:
244,140,625
Step-by-step explanation:
So, going by the rules of PEMDAS, we want to do each step in order.
Since there's no parenthesis, we will just skip to the exponents.
Solve 5^9 first, and that turns out to be 1,953,125.
Then solve 5^3 next, and that turns out to be 125.
Finally, multiply those two, and your final answer is 244,140,625
