Why is scientific notation used?

A. To round numbers to the nearest whole number
B. To promote reproducibility of data
C. To increase the validity of data
D. To express very large or very small numbers



Answer :

Final answer:

Scientific notation is a convenient way to represent very large or very small numbers, commonly used in science and engineering.


Explanation:

Scientific notation is used to express very large or very small numbers in a compact manner by representing them as a simple number multiplied by 10 raised to a certain exponent. It is particularly useful in science and engineering where dealing with numbers like distances in space or atomic sizes is common.

In scientific notation, all numbers are written in the form of a multiplied number by ten raised to a power, making both large and small numbers easy to handle. The power of 10 indicates how many places the decimal point moves, aiding in converting conventional numbers into the scientific notation form.
