exponentennotatie

Exponentennotatie, also known as scientific notation or standard form, is a way of writing very large or very small numbers concisely. It is expressed as a number between 1 and 10 multiplied by a power of 10. The general form is a × 10^n, where 'a' is a number greater than or equal to 1 and less than 10, and 'n' is an integer representing the exponent.

The exponent 'n' indicates how many places the decimal point in 'a' has been moved to obtain the original number. If 'n' is positive, the decimal point has been moved to the right, meaning the original number was large. If 'n' is negative, the decimal point has been moved to the left, indicating a very small number. For example, 300,000 can be written as 3 × 10^5, and 0.00007 can be written as 7 × 10^-5.

Exponentennotatie simplifies calculations involving these numbers. When multiplying numbers in exponentennotatie, the coefficients are multiplied, and the exponents are added. For division, the coefficients are divided, and the exponents are subtracted. This makes arithmetic with extremely large or small quantities much more manageable. It is widely used in science, engineering, and mathematics to represent quantities like distances to stars, sizes of atoms, or probabilities.
