What is the form in writing a scientific notation?
Scientific notation makes it easier to write very large numbers. For example, instead of writing 540,000,000,000, you would write 5.4 x 10 to the power of 11
Converting to Scientific Notation:
- The number must be converted into a whole number with one digit. Let's use the number 500 for example.You would turn it into 5.0
- Then, you times it by ten to the power of decimal places needed to make it 500. 5.0 x 10 to the power of 2
- That's it.
How do you write quantities in scientific notation?
1) Move the decimal until your number appears to be between 1 and 10 count the spaces that you move the decimal.
2) use the number of spaces as the exponent of 10 (the base)
3) if the original number was greater than 10, the exponent is positive, if the original number was less than 1 then the exponent is negative.
EX: 250,000 becomes 2.5 x 105
but 0.0025 becomes 2.5 x 10-3
What is the scientific notation of 0.000000232?
2.32 * 10-7
The ten is to the negative seventh power because you have to move the decimal to the left 7 places to get one whole number.
How do you write 8350000 in scientific notation?
8.35 X 106
-------------
The zeroes are superfluous here. Except for counting places. They reappear when the number is written in standard form.
What are the four things that use scientific notation?
Molecular biology, quantum physics, cosmology and physical chemistry are four examples.
