I believe the answer is
-5
Scientific notation is of the form a 
Number written by Jim = 543000000000000
To find a, take the number and move a decimal place to the right one position.
Number given = 543000000000000
New number = 5.43000000000000
So decimal will be after 5.
Now to find b, count the number of decimals shifted from right to left.
b= 14
So scientific number of 543000000000000 = 
So option A is the answer
Sorry I didn't get any of that but I know that standard forms means numbers that count for something
