Final answer:
The number 0.000232 in scientific notation is 2.32 x 10^-4, and the number 4531 is 4.531 x 10^3.
Step-by-step explanation:
To write the numbers 0.000232 and 4531 in scientific notation, we need to move the decimal point to the right of the first non-zero digit. This gives us a number between 1 and 10 multiplied by 10 raised to a certain power, depending on how many places we moved the decimal point.
For 0.000232, we move the decimal point to the right 4 places to get 2.32. Therefore, the number in scientific notation is 2.32 × 10-4.
For 4531, we move the decimal point to the left 3 places to get 4.531. Hence, this number in scientific notation is 4.531 × 103.
