Answer:
8
x
10
^0
Step-by-step explanation:
the reason why is because there is no 0 behind the 8 so the exponent could not say a number so it is just 0
The greatest GCF would be
20 because if you subtract 32 from 12 you get 20 and now you would want to work on 2/4 minus 1/2 since they are the same 2/4 =1/2 simplified you get 0 which leaves your answer to just 20
