Definition of scientific notation : a widely used floating-point system in which numbers are expressed as products consisting of a number between 1 and 10 multiplied by an appropriate power of 10 (as in 1.591 × 10−20)

How do you write a number in scientific notation?
A shorthand method of writing very small and very large numbers is called scientific notation, in which we express numbers in terms of exponents of 10. To write a number in scientific notation, move the decimal point to the right of the first digit in the number. Write the digits as a decimal number between 1 and 10.
What is the meaning of 10power?
A power of 10 is any of the integer powers of the number ten; in other words, ten multiplied by itself a certain number of times (when the power is a positive integer). By definition, the number one is a power (the zeroth power) of ten.
What is 3.8 as a scientific notation?
This time, you move the decimal point to the right, 4 spaces. N = 3.8 and x = -4. So your number in scientific notation becomes: 3.8×10–4, or 3.
What is scientific notation and why do we use it?
Scientific notation is a way to write very large or very small numbers so that they are easier to read and work with. You express a number as the product of a number greater than or equal to 1 but less than 10 and an integral power of 10 .
How do you write 5000 in scientific notation?
For example, the number 5000 is written in scientific notation as 5 × 103. The number 0.03 is written as 3.0 × 10–2.
What are some examples of scientific notation?
Scientific notation is the way that scientists easily handle very large numbers or very small numbers. For example, instead of writing 0.0000000056, we write 5.6 x 10–9. So, how does this work? We can think of 5.6 x 10–9 as the product of two numbers: 5.6 (the digit term) and 10–9 (the exponential term).

What is the scientific notation for 38000?
38,000 (thirty-eight thousand) is an even five-digits composite number following 37999 and preceding 38001. In scientific notation, it is written as 3.8 × 104.
What is scientific notation in chemistry?
Scientific notation is a way to express numbers as the product of two numbers: a coefficient and the number 10 raised to a power. It is a very useful tool for working with numbers that are either very large or very small.
What is scientific notation made of?
Numbers in scientific notation are made up of three parts: coefficient, base and exponent. 8.60000000.
What is the scientific notation of 5000000?
If you think of 5,000,000 as 5×1,000,000, then you can express 5,000,000 in scientific notation as 5×106, because 1,000,000 = 10x10x10x10x10x10, or 10 times itself 6 times.
How do you write 0.00012 in scientific notation?
Example: 0.00012 is written 120 × 10.

The method of representing a number in digits or figures is called notation. Numeration is known as the method of expressing a number in words.
Where is scientific notation used?
Scientific notation is used by scientists, mathematicians, and engineers when they are working with very large or very small numbers. Using exponential notation, large and small numbers can be written in a way that is easier to read.
What is scientific notation used for in nursing?
Scientific notation is a method to write very big or very small numbers easily. Scientific notation is composed of three parts: a mathematical sign (+ or −), the significand, and the exponential, sometimes called the logarithm.
