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

It is: 6.79*109

7,080,000 in scientific notation is 7.08 × 106

5 x 10^0 mg

It's usually related to large numbers - For example...

1,000,000,000 in scientific notation is 109 - which as you can see takes up much less space.

5.211 × 102 written in regular notation is: 521.1

1200 in Scientific Notation = 1.2 x 103

It is 8.3*10^2 in scientific notation

It is: 1.56*10^2

6.02e6 or 6.02 x 106

64 can be written as 6.40 × 101 in scientific notation.

The standard form of six hundred and three-tenths (600.3) is: 6.003 × 102

9.071 x 10^5

3.54 x 10^-4

Something that is a trillion has 12 zeroes. Then, 100 trillion is 100.0 x 1012. Move 2 decimal places to the left from where the decimal place "landed". Therefore, 100 trillion in Scientific Notation is 1.0 x 1014

The scientific notation 0.000216 is 2.16 × 10-4

15 trillion in scientific notation is 1.5e13 or 1.5 x 1013

5,320,000 in Scientific Notation = 5.32 x 106

The scientific notation of 63 is 6.3 × 101

The decimal is 11 places away from the 3, where you want it to be. Since the number is smaller than zero, the power of ten is going to be negative.

.00000000003 = 3.00 × 10-11

0.00056 is written in standard form as 5.6 x 10-4

3.3 times 10 to the 23rd power = 330,000,000,000,000,000,000,000 (330 sextillion).

450,900,800 is expressed as 4.509008 x 108

It is: 1.23 x 10^14

If you are adding or subtracting two numbers in scientific notation, you must rewrite one of the numbers to the same power of ten as the other, before performing the addition (or subtraction).
