Answer:
172,146
Step-by-step explanation:
you can use the exponential growth formula and get y=127000(1.052)^6. after that, you can just solve (make sure you use PEMDAS) and get 172,146.
Any number to the power of a negative integer will be 1 over that number with the absolute value of the power, so it looks like this:

Therefore, you just need to 8² which is 64, and then do 1 over that (1/64) because it's a negative power.
