Answer 1

Answer:

-5.238- $10^{7}$

or

Since the exponent of the scientific notation is positive, move the decimal point  6  places to the right.

1620000

Step-by-step explanation:

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the  

10 . If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

Hope this helps :)
