Question

How do you write twelve million in scientific notation?

Answer 1

Hint: In the given question, we have been given to write the scientific notation of a number written in phrase. To solve this, we must know what a scientific notation is – it is a way of writing extremely large numbers including lots of zeroes, in the form of a single digit followed by a decimal point, followed by the rest of non-zero numbers, followed by multiplication with ten raised to the power of condensed numbers, including the zeroes.

Complete step-by-step answer:
In the given question, we have to write the scientific notation of twelve million.
First, twelve million is one followed by six zeroes, or, \[12,000,000\].
Now, we use scientific notation,
\[12000000 = 12 \times {10^6} = 1.2 \times {10^7}\]
Hence, one million can be written as \[1.2 \times {10^7}\].

Additional Information:
The way of writing in the scientific notation is especially helpful to physicists, scientists, researchers who are working with very large numbers. For example, writing \[1\] followed by twenty-nine zeros is very space and time consuming, so, it is better to write it as \[1 \times {10^{29}}\]. This small notation saved so many zeroes’ space and time.


Note: In the given question, we had to write the scientific notation of twelve million. To do that, we must know what a scientific notation is and how a scientific notation is written. Then, we must also know what is the value of twelve million in actual numbers – twelve followed by six zeroes. Then we just write down the notation and get our answer.
