Here's how to convert it:
1. Move the decimal point to the right until you have a number between 1 and 10. In this case, we move it 7 places to the right, resulting in 4.63.
2. Count the number of places you moved the decimal. Since we moved it 7 places to the right, the exponent will be -7.
3. Write the number in the form a x 10b, where 'a' is the number between 1 and 10 and 'b' is the exponent.
Therefore, 0.000000463 in scientific notation is 4.63 x 10-7.
