What is the scientific notation of 27?
It is 7.27*10^2
10^2 = 100
7*10^2 = 700
0.27*10^2 = 27
700+27 = 727
so 7.27*10^2 = 727
The first number may not be higher then 10
Hope it helped
What is the standard form of five hundred million and four-tenths?
The standard form of the number four hundred sixty-one millionths (0.000461) is: 4.61 × 10-4
How do you write 3.85x10 to the 5th power in standard notation?
3.85x105 in standard notation = 385,000
What is 0.000083 expressed in scientific notation?
Move 4 decimal places to the right to get 8.331 x 10-4. That term is in scientific notation because it's expressed as the term multiplied by the term to the integer exponent. That is:
a x 10b
Scientific notation is a way of making numbers scientific true or false?
You don't - just as you don't with a number in normal notation.
How do you write 3 and 124 thousandths in standard form?
You write three and eighteen hundredths (3.18) in standard form as: 3.18 × 100
The given expression is:
8.4 x 108 x 4.2 * 10³
Rewrite the expression this way:
8.4 x 4.2 x 108 + 3
So the expression is simplified to:
35.28 x 1011
= 3.528 x 1012
What integer should replace m for 0.0000452 in scientific notation?
Since we need to shift 5 decimal places to the right to obtain the value in scientific notation, n = -5 for base 10.
How do you write fifty-eight and twenty-one hundredths in standard form?
Fourteen and sixty-two hundredths (14.62) in standard form is: 1.462 × 101
How do you write 46322 in scientific notation?
Such small numbers aren't normally expressed in scientific notation but it is: 4.6332*104
In scientific notation, you should have only one digit to the left of the decimal point.

Write 3456 000 000 000 000 km using scientific notation?
Scientific notation is having the form x.xxxxx * 10^x power. To put 32392.55 in this form, you need to move the decimal to the left by 4 places. Each time you move the decimal to the left, are dividing the whole number by 10. To make up for this, you multiply the whole number by 10 to the side.
All of these numbers are equivalent:
34392.55
3439.255 * 10
343.9255 * 10 * 10
34.39255 * 10 * 10 * 10
3.439255 * 10 * 10 * 10 * 10
Now that you have the number in the correct form, where only the digit 1-9 is to the left of the decimal, you combine all the powers of 10 and that's your final answer.
3.439255 * 10^4
If we multiply the 10s back into the number, we end up shifting the decimal four places to the right: 34392.55, which is what our original number was. So we haven't changed anything at all, just how the number is displayed.
What are three parts of a scientific notation?
Here is the whole thing:
Lets pretend we are going to use the number:
12,645,000,000
- 1. get the numbers that are most important, which are: 12,645
- 2. see how many times you have to move the decimal point to make the number greater than 1 but less than 10. It would be like this:
start with: 12645
then move the decimal point over to the left 4 times, making it: 1.2645. this number is greater than 1 but less than 10.
- the number of times you moved your decimal point is your exponent of ten in the scientific notation. like this:
since you moved the decimal point 4 times, the scientific notation of this number is going to be your number-1.2645- times ten to the 4th power -104-
So your number is now in scientific notation: 1.2645x104

To make your scientific notation standard notation, do the following:
1. look at your number: 5.8438x105
2. move the decimal point over to the right whatever your exponent is: 5-8-4-3-8-0
3. your new number should be: 584,380
IMPORTANT!
When your decimal reaches the end of your number, keep going! like this:
if the decimal point was here: 8.95 and you need to move it over 6 times, keep going! it should look like this:
8-91-52-03-04-05
so your decimal point would be 3 0's back and look like this:
895,000.
There you go!
