Scientific Notation

It is: 3.12*10-4

It is: 3.7*10-7

8 x 8 = 8^2

4.7 x 106

5.75 × 109 written in regular notation is 5,750,000,000

0.005123 in Scientific Notation = 5.123 x 10-3

Scientific notation needs to be written as 5.4x104

The lead number needs to be greater than 1, but less than ten. In this case, it is 5.4. The exponent tells me how many times I need to shift my decimal point to get my big, or in your case, a small number. For my example, I would have 54,000

For yours, it is a small number. Shift the decimal point 6 spots to the right, so you have 8.7, which is between 1 and ten. 8.7x10-6 would be correct.

It is: 9.9*10^-5

5.932x 104

7.8 x 10^(-5)

5.6 × 10-8

9.91 x 10^-7

Shift a decimal place right from the starting point. Therefore, we write out:

1.23 x 10-1

It is: 6.4*10-9

7 to the power of 50 is 1.798465043*10^42 in scientific notation

It is: 3.07*10^8 = 307,000,000

0.000025 is 2.5 x 10-5

4.52e-5

it is important to us to use scientific notation because if we use it we can read the numbers easily.

Scientific notation is important because it make writing numbers easier. For example, you are contestant in a quiz bee and the examiner says,134000000000000x500000000000 or something like that you will lost time writing zeroes and you will also confused about it instead we can just write it in a scientific notation.

0.069 = 6.9 × 10-2

500,300,100 = 5.003001 × 108

8.002 × 106

7x10^-6

0.000735 in scientific notation is 7.35 x 10^-4
