What is scientific notation?
Scientific notation is a form of presenting very large numbers or very small numbers in a simpler form. As we know, the whole numbers can be extended till infinity, but we cannot write such huge numbers on a piece of paper. Also, the numbers which are present at the millions place after the decimal needed to be represented in a simpler form. Thus, it is difficult to represent a few numbers in their expanded form. Hence, we use scientific notations. Also learn, Numbers In General Form.
How to convert scientific notation to standard form?
To convert a number from scientific notation to standard form, we should move the decimal point (if any) to the left if the exponent of 10 is negative; otherwise, proceed to the right.
How many places to move the decimal place when the exponent is positive?

What happens to the power of 10 if the number is multiples?
If the given number is multiples of 10 then the decimal point has to move to the left , and the power of 10 will be positive. Example: 6000 = 6 × 10 3 is in scientific notation. If the given number is smaller than 1, then the decimal point has to move to the right, so the power of 10 will be negative.
How to find the power of 10?
To determine the power or exponent of 10, we must follow the rule listed below: The base should be always 10. The exponent must be a non-zero integer, that means it can be either positive or negative. The absolute value of the coefficient is greater than or equal to 1 but it should be less than 10.

How many significant figures are there in a constant?
You can think of constants or exact values as having infinitely many significant figures, or at least as many significant figures as the least precise number in your calculation. Use the appropriate number of significant figures when you input exact values in this calculator. In this example you would want to enter 2.00 for the constant value so that it has the same number of significant figures as the radius entry. The resulting answer would be 4.70 which has 3 significant figures.
