Depends on the length of the number. If you have something like 345,670,000,000,000, then it would be 345.67 x 1012

Can a negative number be expressed in scientific notation?
Yes, a negative number can be expressed in scientific notation. In scientific notation, a negative number is indicated by the negative sign (-) placed before the first significant digit. The number is then written in the form of a decimal number between 1 and 10, multiplied by a power of 10. For example, -3.2 x 10^-5 is a negative number expressed in scientific notation.
What is the scientific notation for 21500?
Scientific notation is a number with a non-zero digit before a decimal point multiplied by a power of 10: 21500 = 2.15 x 104
How do you use scientific notation for 10.03?
Scientific notation takes one digit before the decimal point and uses multiples of 10 to represent the rest of the digits. In this case, scientific notation is not really practical. The answer is 1.003 x 101
What is 52.000 in scientific notation?
5.2 x 10^1 because in scientific notation you only have one digit before the decimal and the rest fall after..so if you move the decimal to the left the notation number will be positive the right would be negative notation. For example .00058 would be 5.8 x 10^ -4
What is 0.0000105 in scientific notation?
A number in scientific notation should have one number before the decimal place then two after. You move the decimal so this is true, then the number of places you moved the decimal will be the exponent. If you move the decimal to the right your exponent will be negative, if you move it to the left it will be positive. In this case you would move the decimal 5 places so you have 1.05x10^-5.

How many numers are before the decimal point when using scientific notation?
There must be exactly one.

What is the difference between a scientific notation and a standard notation?
Well, adding x10 is scientific notation. Example:456-4.56x102. this is because there are two numbers before the decimal. another example:14945-1.4945x104. if you do not get it, I'm sorry. This is the best i can explain

You move the decimal so this is true, then the number of places you moved the decimal will be the exponent.

How do you write 3785000 in scientific notation?
To write 3785000 in scientific notation, move the decimal point to the left until there is only one digit before the decimal point. In this case, it would be 3.7850000. Then, count the number of places moved; in this case, it is 6. So, 3785000 in scientific notation is 3.785 × 10^6.
How do you Express the number 14503 in scientific notation?
You always have one non-zero digit before the decimal point, in this case the 1. Then you are specifying how many places to move the decimal point, which is 4 places. That gives us the E+04 part.1.4503E+04
How do you write 4100 in scientific notation?
To write 4100 in scientific notation, you need to move the decimal point so that there is only one non-zero digit before it. As 4100 can be written as 4.1 x 10^3.
How do you turn this 0.0000000076 into scientific notation?
To convert 0.0000000076 into scientific notation, you move the decimal point 10 places to the right until you are left with a single nonzero digit before the decimal. In this case, it would be 7.6 x 10^-9.
Why the decimals are also used in scientific notation?
In scientific notation, the coefficient (number before the base 10) is written such that there is only one digit before the decimal point, and that digit can be 1 to 9. After that, the rest of the number is written after the decimal point, and there is no limit to the number of digits after the decimal point. The exponent on the 10 indicates how many places to move the decimal in order to change the number to standard form. Conversely, when going from standard form to scientific notation, the exponent indicates the number of places to move the decimal to change the number from standard form to scientific notation.Examples:1.48762 x 105 = 148762 in standard form7.593 x 10-3 = 0.007593 in standard form39732 = 3.9732 x 104 in scientific notation0.046 = 4.6 x 10-2 in scientific notation
