Scientific notation is a way of writing very large or very small numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10. For example, 650,000,000 can be written in scientific notation as 6.5 ✕ 10^8.

What are five examples of scientific notation?
Here are five examples:
- Multiply (4 x 104) and (7 x 105) First 4 x 7 = 28. Next add exponents, 4 + 5 = 9. Result is 28 x 109
- Divide (6 x 105) by (4 x 104) 6/4 = 1.5. Subtract exponents 5 – 4 = 1. Answer 1.5 x 101 or 15.
- Multiply (4 x 10–7) and (3.25 x 109) 4 x 3.25 = 13. Add exponents = -7 + 9 = 2. Answer is 13 x 102 or 1300.
How do you write a number in scientific notation?
To convert any number into scientific notation, you write the non-zero digits, placing a decimal after the first non-zero digit. Then, you count the number of digits you need to move the beginning decimal to get to where your decimal is now. If you move the decimal to the left, then your power is positive.
What is a real life example of scientific notation?
It’s easier to read and write very big or very small numbers using scientific notation. For example, the $65,000,000,000 cost of Hurricane Sandy is written in scientific notation as begin{align*}$6.5 times 10^{10}end{align*}.
What is the scientific notation of 5000?
5 × 103
For example, the number 5000 is written in scientific notation as 5 × 103. The number 0.03 is written as 3.0 × 10–2.
How do you write 27000 in scientific notation?
27,000 is written 27 × 10.
What is the scientific notation of 45?
Convert 45 to Scientific Notation:
45 in Scientific Notation = 4.5 x 101 where 1 is the order of magnitude.
What are the steps to scientific notation?
Step 1: Move the decimal point to the left until you have a number greater than or equal to 1 and less than 10. Step 2: Count the number of decimal places you moved the decimal point to the left and use that number as the positive power of 10. Step 3: Multiply the decimal (in Step 1) by the power of 10 (in Step 2).
How do you write 420000 in scientific notation?
420,000 (four hundred twenty thousand) is an even six-digits composite number following 419999 and preceding 420001. In scientific notation, it is written as 4.2 × 105.
How do engineers use scientific notation?
Engineering notation or engineering form is a version of scientific notation in which the exponent of ten must be divisible by three (i.e., they are powers of a thousand, but written as, for example, 106 instead of 10002).
What is scientific notation and why is it used?
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 is scientific notation useful in science?
Benefits of scientific notation
Scientific notation ensures accuracy and reduces the possibility of error when using very small or very large numbers. Scientific notation makes it easier to interpret larger numbers, especially for individuals who are not used to working with such large numbers.
What’s the scientific notation of 29029?
29,029 (twenty-nine thousand twenty-nine) is an odd five-digits composite number following 29028 and preceding 29030. In scientific notation, it is written as 2.9029 × 104.
How do you write 500000 in scientific notation?
Answer: 500000 is converted as scientific notation 5×105.

How do you write 0.004 in scientific notation?
Scientific Notation
- The power of 10 is positive when the number is larger than 1_4000=4×103 1 : 4000 = 4 × 10 3 .
- The power of 10 is negative when the number is between 0 and 1:0.004=4×10−3 1 : 0.004 = 4 × 10 − 3 .
