Answer:
2.402×10⁷
Explanation:
in scientific notation, the decimal point comes after the first non-zero digit, in this case after 2 and before 4.
so it becomes
2.402×10⁷
and raised to the power 7 because we jumped 7 times to the left from the last digit, so basically the decimal point moved from after the last digit ( 24,020,000. ) to after 2 (2.4020000 ).
