To convert our number to scientific notation, we are going to move the decimal point to the right until we have only one non-zero digit to the left of the decimal point, and then, we are going to multiply that number by a negative power of 10 equal to the number of times we moved the decimal point to the right:
<span>
Our number is 0.000000016, so we need to move the decimal point 8 times to the right to have </span>only one non-zero digit to the left of the decimal point (1.6). Since we moved the decimal point eight times to the right, we are going to multiply 1.6 by y a negative power of 10 equal to the number of times we moved the decimal point to the right i.e.

.
So 0.000000016 expressed in scientific notation is 1.6x

, or in calculator notation 1.6E-8
We can conclude that the correct answers are <span>
1.6E-8 and </span><span>
1.6 × 10-8</span>

Hey !
I am going to explain what I did to get the answer...
I multiplied $29,160 by 30 = $874,800
Then I multiplied $84,460 by 30 = $2,533,800
Then I subtracted the results = a difference of $1,659,000
So the answer to your question is, $1,659,000 is the difference.
I hope I was able to help you out :D <span />
