Final answer:
The expression 2.36 × 10-6 is written in scientific notation. The number in scientific notation is determined by moving the decimal point to the right or left until there is one non-zero digit to the left of the decimal point. The correct scientific notation for 2.36 × 10-6 is -0.00000236.
Step-by-step explanation:
The expression 2.36 × 10-6 is written in scientific notation. The number in scientific notation is determined by moving the decimal point to the right or left until there is one non-zero digit to the left of the decimal point. In this case, we move the decimal point six places to the left to get 0.00000236. Since the decimal point moved to the left, the exponent of 10 is negative. Therefore, the scientific notation for 2.36 × 10-6 is -0.00000236. Answer choice C, -0.0000236, is the correct option.
