Scientific notation is a way to express very large or very small numbers using powers of ten. In this format, a number is written as a product of a number between 1 and 10 and a power of ten. For example, the number 5,000 can be written as 5 × 10^3, because 5,000 is the same as 5 multiplied by 1,000 (which is 10 raised to the power of 3). Similarly, a small number like 0.0003 can be expressed in scientific notation as 3 × 10^-4. Here, -4 indicates that the decimal point moves four places to the left. This notation makes it easier to handle calculations with extremely large or small values, like the distance from Earth to a star or the size of tiny particles. Understanding scientific notation helps simplify complex math and makes it easier to compare different numbers.
