Convert to scientific notation:
12 million |
Count six zeros, move the decimal an additional two to the left: 1.2 x 10^7
|
|
Convert to scientific notation:
286 thousand |
Count three zeros, move the decimal an additional two to the left: 2.86 x 10^5
|
|
Convert to scientific notation:
134 millionths |
0.000134 = 1.34 x 10^-4
Note that millionths requires six positions. The last digit, 4, is at the 'millionth' marker. |

Explain how to convert positive numbers greater than one to scientific notation
|
Get the coefficient and exponent.
For the exponent, count from the current decimal position, to the position immediately after the first number. Create the coefficient by transcribing the numbers, inserting a decimal after the first number. 23000 = 2.3 x 10^4 |

Explain how to convert positive decimal numbers to scientific notation.
Find the: - Range of included numbers - The coefficient - The exponent |
A decimal number between 0 and 1 will have a negative exponent.
For the exponent/magnitude, count right, from the current decimal to the space after the first non-zero number. The coefficient begins with the first non-zero number, then a decimal, and then the remainder of the numbers. Don't forget that the exponent is negative. .0003408 = 3.408 x 10^-4 |
