It's a, because an exponent means it's multiplied by itself that many times. so 3 times 3 is 9 then times 3 again is 27. but negative exponents are always fractions and since the normal number is positive it's D (sorry at first I didn't see d and c)
68 + 54 + 59 + 70 + 69 + 65 + 73 + 59 + 74 + 54 = 586 grams
586 grams/10 = 58.6 grams (if you round it, you will get 59 grams)
hope this helps!!
