Answer: 0.00004015
Explanation:
Scientific notation is used when very large or small numbers need to be written in a way that we can manage them. It is usually expressed when a decimal number between 1 to 10 is multiplied by an integer power of 10. The power of 10 is also referred to as the exponent and it represents the number of spaces the decimal point is moved either to the left or right depending on the problem. Lets solve the above problem.
Since 10 is raised to a negative number that means that the decimal will have to be moved 5 spaces to the left hand side. We count the 4 as the first space and four additional zeroes to get:
0.00004015
