What is the result of (6.2 * 104) x (3.3 * 102) expressed in scientific notation?

Well first you would do (6.2 x 104) and that gives you 644.8. then you would do (3.3 x 102) and that gives you 336.6. then times 644.8 and 336.6 and that gives you 217039.68. then all u gotta do is move the decimal between the 2 and 1. and you move the decimal 6 places so it would look like 2.1703968 (times) 10^6
