Answer:
very small
Explanation:
Scientific notation is used to shorten numbers that are either very large or small, so negative and positive aren't really relevant answers.
Now you have to determine if the number 9.3 x 10^-8 is very large or small.
When dealing with scientific notation, a negative exponent means the number was originally a decimal and a positive exponent means the number was very large. The exponent is negative 8 so it is very small.
0.023 = 2.3 x 10^-2
2300. = 2.3 x 10^3
