Pls Help Me Also Remember To Explain Its Due Today class=

Answer :

i’m gonna explain B so basically you just plug in the numbers for the corresponding letter, for example, on B it would be -2 ^ -4 and then multiply that times 5 ^ 0 . so -2 ^ -4 = 1 over 16 and 5^0 is 1, so the answer would simply be 1/16 or 1 over 16
