What is 40000 as a scientific notation?
40,000 =
4 x 104 Forty thousand
: the distance around the Earth at the equator (in km). 4,000 = 4 x 103 Four thousand: The circumference of Pluto (in km). As you can see, the exponent of 10 is the number of places the decimal point must be shifted to give the number in long form.
How do you write 0.00042 in scientific notation?
- Make the number a new number between 1 and 10. Move the decimal point to make 0.00042 a new number between 1 and 10. …
- Define the power of 10. Because our original number was less than one, the exponent defining the power of 10 is negative. …
- Final result.
Why is scientific notation often used when recording experimental measurements?
There are two reasons to use scientific notation in chemistry. The first is
to reveal honest uncertainty in experimental measurements
. The second is to express very large or very small numbers so they are easier to read.
How do you write 960000 in scientific notation?
960,000 (nine hundred sixty thousand) is an even six-digits composite number following 959999 and preceding 960001. In scientific notation, it is written as
9.6 × 10
5
.
How do you write 50000 in scientific notation?
For example, when we write 50,000 in scientific notation, it is written as
5 x 10
4
. When we write . 00008 in scientific notation, it is written as 8 x 10
– 5
. If we have a number such as 456,000,000 we use the same process.

How do you convert scientific notation to standard form on a calculator?
Fortunately, you can force your calculator to display answers in scientific notation.
Press [MODE] and use the arrow keys to choose Sci
(short for Scientific mode) and press [ENTER]. You can rest assured that all your answers will be displayed in scientific notation.
How do you write something in scientific notation?
If you moved the decimal point to the right in Step 2, put a minus sign on the exponent. You moved the decimal point to the left, so you don’t have to take any action here. Thus, 360,000,000 in scientific notation is
3.6 x 10
8
.
When multiplying numbers in scientific notation do we add or multiply the powers superscripts of 10?
Add the exponents of the powers of 10
. Join the new coefficient to the new power of 10 to get the answer.
Why do we need to express numbers in scientific notation?
The primary reason for converting numbers into scientific notation is
to make calculations with unusually large or small numbers less cumbersome
. Because zeros are no longer used to set the decimal point, all of the digits in a number in scientific notation are significant, as shown by the following examples.
Why is scientific notation used in chemistry?
Scientific notation
allows us to express very large or very small numbers in a convenient way
. This notation uses a coefficient (a number between 1 and 10) and a power of ten
What is the appropriate way to write 0.658 in scientific notation?
- Move the decimal 1 times to right in the number so that the resulting number, m = 6.58, is greater than or equal to 1 but less than 10.
- Since we moved the decimal to the right the exponent n is negative.
