Similarly, see that, to write the number in scientific notation, it is necessary to move 9 decimal places to the left, then:Ĭ) The diameter of an atom is on the order of 1 nanometer, that is, 0.0000000001. Observe the number and see that, to write it in scientific notation, it is necessary to “walk” with the decimal point eight decimal places to the left, so the base 10 exponent will be positive:ī) The approximate age of planet Earth is 4,543,000,000 years. In summary, if the zeros are to the left of the number, the exponent is negative and coincides with the number of zeros if the zeros appear to the right of the number, the exponent is positive and also coincides with the number of zeros.Ī) The distance between the planet Earth and the Sun is 149,600,000 km.

We agree that this process is not at all practical, so, in order to facilitate it, note that when we “walk” with the comma to the right, the base 10 exponent decreases the number of decimal places walked. Now, when we “walk” decimal places to the left, the base 10 exponent increases the number of walked places. What is scientific notation Scientific notation is a method of expressing. If using our scientific notation converter, you just enter the decimal number and click 'Convert'. Thus, to write a number in the form of scientific notation, the first step is to write it in the form of a product, so that a base 10 power (decimal form) appears. See the examples:Ī) 0.0000034 = 3.4 x 0.000001 = 3.4 x 10 – 6ī) 134,000,000,000 = 134 x 1,000,000,000 = 134 x 10 9 For example, the number 10,550,000 in normalized scientific notation would be 1.055 x 10 7 and 1.055e7 or 1.055e+7 in e notation.

Having reviewed the idea of base 10 power, we will now understand how to transform a number into scientific notation. It is important to emphasize that, regardless of the number, to write it in the form of scientific notation, we must always leave it with a significant figure. For example, 10 10 is equal to 10,000,000,000.Īnother case that we must analyze is when the exponent is a negative number. This is equivalent to saying that the number of decimal places moved to the right is equal to the power exponent. Also see that the number in the exponent is the number of zeros that we have on the right. Note that as the exponent increases, so does the number of zeros in the answer. From the definition of power, we have to:

To transform a number into scientific notation, it is necessary to understand what are base powers 10.
