A sign (plus or minus),a significand or mantissa (a number, in decimal form, which is greater than or equal to 1 and less than 10),
an exponent (the base, which is 10, may be implied).
As an example of the last of these, 2.57*10^3 may be 2.57E3
Scientific notation shows things to the power of 10 So 35 in scientific notation is 3.5 x 10 Other examples are 350 is 3.5 x 102
Shift 3 decimal places to the right from the starting position, so the exponent for base 10 is -3. Therefore, the number in scientific notation is: 2.5 x 10-3
1)you can do scientific notation. 2)you can observe with different things.
Some numbers are so huge (like the mass of the sun=1.98892 × 1030 kilograms) that writing a number with thirty or so digits is difficult to manage. There are some numbers so small that we have the same problem (the mass of an electron is 9.10938188 × 10-31 kilograms). Scientific notation is actually clearer and simpler to write in these two cases.Scientific notation is important IF you are going to understand some things in the universe. Some authors use Scientific notation to discuss the topics they are writing about. You will not understand what those authors are talking about without understanding Scientific notation.
Well, darling, the scientific notation of 0.1 nanometers is 1 x 10^-1 nm. In simpler terms, it means you move the decimal point one place to the left to get a number between 1 and 10, and then slap on the power of -1 to represent the nanometer unit. Hope that clears things up for you, sugar!

It is easier than writing billions and millions by using scientific notation. Therefore, there is no mix up of what the numbers represent.
Shift 3 decimal places to the right from the starting position, so the exponent for base 10 is -3. Therefore, the number in scientific notation is: 2.5 x 10-3

In Britain, scientific notation is known as "standard form."

If the exponent is positive, move the decimal to the right the same number of spaces as the number of the exponent. If the exponent is negative, move the decimal to the left the same number of spaces as the number of the exponent.Examples:2.5 x 103 is 2500 in standard notation. (Move the decimal to the right 3 spaces.)4.9 x 10-5 is 0.000049 in standard notation. (Move the decimal to the left 5 spaces.)
