Question

How do you write 2.5 million in scientific notation?

Answer 1

Hint: In the above question, you were asked to convert it into scientific notation. You can write 2.5 million in terms of the exponent of 10. Also, 2.5 million = 2,500,000 have 5 zeroes (0’s). You will convert this to decimal so that you can find the exact value of 2.5 million in scientific notation. So, let us see what will be the approach to solve this problem.

Complete Step by Step Solution:
The given problem statement in which we need to write 2.5 million in scientific notation.
As we already know that 2.5 million is 2,500,000 in which the number of zeroes is 5.
Now, we have to move the decimal place 6 places to the left to write 2.5 million into scientific notation. So, 2,500,000 = $2.5\times {{10}^{6}}$. So, from here we can clearly note that the exponent of 10’s is positive.

Therefore, 2.5 million can be written as $2.5\times {{10}^{6}}$ in scientific notation.

Note:
You need to remember that million means the number which is equivalent to the product of a thousand and a thousand. Moreover, scientific notation is a way to express in the form of decimal form. It is also known as the standard index form.
