$703 , 000 , 000 = 7.03 \times {10}^{8}$

Assuming that the number given has 3 significant figures only.

#### Explanation:

To express a number in scientific notation, put the decimal point after the first non-zero digit (which in this case is 7).

Subsequently, count the number of places from the decimal point to the end of the number to get the exponent. (8 in this case)

Lastly, drop all the non-significant zeros at the end of the number (if any).
