1. Move the decimal point:
* Move the decimal point to the right of the first non-zero digit, which is '5'.
* You'll move the decimal point 2 places to the right.
2. Determine the exponent:
* Since you moved the decimal point 2 places to the right, the exponent of 10 will be -2.
3. Write the number:
* The number is now -5.034
* Combine it with the exponent: -5.034 x 10⁻²
Therefore, the scientific notation of -503.4 is -5.034 x 10⁻²
