Question

How do you write \[2,750,389\] in scientific notation?

Answer 1

Hint: In the scientific notation it expresses a very large or the small number by the power of ten due to that the value power of ten due to that the values we get are more easily understandable. We can also say the method of scientific notation is a way of writing out the number. While dealing with any large or very small number this method is very useful for us. The numbers from scientific notation is in the form of \[a{{.10}^{v}}\]
Where as \[1 < a < 10\] and \[b\] is an integer.
As an example we have to take \[0.00000000123.\]
The scientific notation for \[0.00000000123\] is \[1.23\times {{10}^{8}}\]

Complete step by step solution:
The given number is \[2,750,389.\]
Now, we have to write \[2,750,389\] in the scientific notation. First we have to move the decimal due to that there is only one non zero digit to the left of the decimal point.
The number which we moving that will be the exponent on the \[10.\]
In some cases whenever the number decimal moves towards the right, then the exponent will be negative.
On the other side it becomes positive.

Hence, the scientific notation for \[2,750,389\] is \[2.750389\times {{10}^{6}}.\]

Note: While writing the scientific notation if only included the figure significant which is in real numbers. Where \[a\]is converted in the other section. For expressing the number in the scientific notation we must move the place of decimal to right if the number is less than zero or greater than zero then the number moves off the left. Not insert zero in between any number and at decimal point. Also remember the point moves the decimal point to the right left direction.
