How do you change 310 into scientific notation?

"310".

There isn't much point in writing such a small number in exponential format, because it would take more keystrokes than typing the number. If we HAD to do it, we might write "3.1E2". As you can see, that takes 2 more keystrokes than just typing the number.

What is something documented in scientific notation?

The diameter of an atom ranges from about 1 × 10^-10 m to 5 × 10^-10 m.

How are numbers written in scientific notation?

Scientific notation is a way of representing numbers, usually very large or very small, in the form

a*10b where 1 ≤ |a| < 10 is a decimal number and b is an integer (negative or positive).

a is called the mantissa and b is called the exponent.

To convert a number to scientific notation:

· If the number has no decimal point, then add one at the end.

· Then move the decimal point to just after the first digit while counting the number of places you have moved it.

· The new number, formed after moving the decimal point is a.

· The number of places to the left that the decimal point was moved is b. If it was moved to the right, then b is negative.

For example:

23045.06 becomes 2.304506*104

0.00023004 becomes 2.3004*10-4

What is the scientific notation of 0000748?

7.48*102 ( ignore the noughts to the left of 7 unless it was a decimal number)
