Represent the following numbers in the scientific notation.

749300000000

Answer :

The given number is 7 4 9 3 0 0 0 0 0 0 0 0 . (In integers decimal point at the end is usually omitted.)


Move the decimal point so that there is only one non - zero digit to its left.



The decimal point is to be moved 11 places to the left of its original position. So, the power of 10 is 11.


(The count of the number of digits between the old and new decimal point gives n the power of 10.)


Therefore, scientific notation is 7.49300000000×1011 = 7.493×1011.
