Answer:
1,728
Explanation:
To determine how many times bigger 12^8 is than 12^5, we need to divide 12^8 by 12^5.
The general rule for dividing exponents with the same base is to subtract the exponents. In this case, we have:
12^8 / 12^5 = 12^(8-5) = 12^3
So, 12^8 is 12^3 times bigger than 12^5.
Calculating 12^3:
12^3 = 12 * 12 * 12 = 1,728
Therefore, 12^8 is 1,728 times bigger than 12^5.
