Step by Step Solution
Step 1 of 4
(a)
Scientific notation is a very handy way of describing very large or very small numbers. This notation expresses a number with an exponent of 10 as a decimal point. The decimal place is always between 1 and 10, which means that there is always only one digit on the left before the decimal point.
Example: 0.005m can be written as
(a)
0.000000001 s
We have 8 zeroes before the first non-zero digit 1 in this case.
So we're moving the decimal point so it's after 1.
After doing so , we get . Remember that the unit does not change during conversion.
