From M.Kline's "Mathematical thought from ancient to modern times", pp.260261: "In 1484 Chuquet ...wrote 12^0 for 12x^0 and 7^{1m} for 7x^{1}...In 1585 Stevin wrote ...Newton used positive, negative, integral, and fractional exponents...". I cannot reproduce Stevin's notation; where Chuquet wrote 12^0, say, Stevin would write the exponent as zero inside a circle. There are also references to Chuquet in Boyer's and Katz's books.
