[AI-generated answer — Explain Bot]

To express a number in scientific notation, we need to write it in the form of A × 10^B, where A is a number between 1 and 10 (excluding 10), and B is an integer representing the power of 10.

For the number 0.00023, we need to move the decimal point to the right until we have a number between 1 and 10. Count the number of places you moved the decimal point. This will be the value of B.

In this case, we move the decimal point 4 places to the right to obtain 2.3. So, B = -4.

Therefore, 0.00023 can be expressed in scientific notation as 2.3 × 10^-4.
