Answer:
8.3 x 10⁻⁷
Explanation:
0.0000083 in scientific notation
To put numbers in scientific notation, you have one (1) non-zero digit in the ones place.
8.3 x 10ˣ
From 8.3, we would have to move the decimal place seven (7) places to the left (this means you put a negative sign in front of the exponent).
8.3 x 10⁻⁷
