Final answer:
To convert a decimal number like 0.00000305 to scientific notation, you move the decimal point six places to the right, resulting in 3.05 × 10^-6. In scientific notation, the number is expressed as a product of a coefficient (here, 3.05) and 10 raised to a power (the number of places the decimal was moved, which is -6 in this case).
Step-by-step explanation:
To convert 0.00000305 into scientific notation, the process involves identifying the first non-zero digit, which is 3, and placing the decimal point immediately after it, yielding 3.05. The next step is to determine the number of places the decimal has moved from its original position, which, in this case, is six places to the right. As we move the decimal to the right, each movement represents a division by 10, resulting in a negative exponent.
Therefore, the correct scientific notation is 3.05 × 10^-6. This notation succinctly represents the original number's magnitude in a more compact form, with the exponent indicating the power of 10 by which the decimal was adjusted.
