Scientific Notation

It is: 5.64*1010

1. 700 millionths = 7.0 × 10-4
2. 700 million = 7.0 × 108
3. Seven ten-thousandths = 7.0 × 10-4

2,794.3 million in standard form is 2.7943 × 109

3.744000 is scientific notation is 3.744 x 100. This is because the decimal is already placed where it would be after converting the number to scientific notation.

However, if you wanted to convert 3744000.0 to scientific notation, you would have to move the decimal left six places. This number, in scientific notation, is 3.744 x 106.

7,062,010.2 = 7.0620102 × 106

It is: 9.68*101 cm

3.2 × 10-3 or 3.2E-3

The scientific notation of 0.000000001 of a meter is: 1.0 × 10-9 meters.

Ask yourself.

Would you rather write this out in long hand?

234,000,000,000,000,000,000

-----------------------------------

Or this?

2.34 X 1020

--------------

Let alone adding, subtracting, multiplying and dividing the first long number.

The scientific notation of 9,000 is: 9.0 × 103

5.04x 10 to the power of 3

2,520,000.000,000 = 2.52*1012 in scientific notation

If the trailing 0s are necessary to show precision, then 1.540000000*10-1 otherwise 1.54*10-1

4,253 = 4.253 × 103

7.15 × 10-2

or

7.15E-2

723-7

How did I get this answer though?

STEP 1: count how many numbers there is in .0000723---- there is seven

STEP 4: since the decimal <--------------- this way , we will write a negative sign and place it as an exponent, like above. See how -7 is slightly 723. It is written as this 723-7

EASY

To convert a decimal to scientific notation, you first need to divide the number by a power of ten such that the result has units as the greatest place value. In this case, you would divide by 0.01 to get 3.6

The next step is to take the amount you divided by (0.01) and express it as a power of 10 (10-2)

Thus, 0.036 in scientific notation is 3.6x10-2

That is the scientific notation. The number is 550,000

9.87e+5

6.87 x 10^-5 : The decimal place must be moved so that the number is between 1 and 10 {it can equal 1, but not 10, though}. Five places moved makes it 6.87, now we moved it 5 places to the right, so the power is 5, but to the right means negative power. So the power of ten is -5.

6.2 × 105 written in regular notation is 620,000

To express astronomically large numbers in smaller context to do high level mathematical calculations mainly in space, it also used to calculate things on the opposite spectrum with small particles.

617,000 = 6.17 × 105

It is 8.75 x 104

i shouldn't answer this ,because its probaly a homework question but oh well [2.8*10^2]
