Answer 2

To write 549 in scientific notation, you should move the decimal point to the left so that there is one nonzero digit to the left of the decimal point. This would make it 5.49. Then, express it as a number between 1 and 10 by dividing it by 10. Finally, multiply it by 10 raised to the power of the number of places you moved the decimal point. In this case, it would be 5.49 x 10^2.
