Numbers like 10, 100, 1000 are referred to as the powers of ten. They're used frequently in our decimal number system and are widely used in scientific notation to express large or small numbers. The power of 10 in these numbers represents the number of places the decimal needs to be moved for them to become a number from 1 to 9.
Numbers such as 10, 100, 1000, and so on are referred to as powers of ten. This is because our counting system is based on increases of ten due to human beings starting to count using their ten fingers. Hence, each place in our numbering system is ten times greater than the place to the right of it. For example, the number 450 can be written as 4.5×10², meaning it's two orders of magnitude, or 10². These numbers can also be used in scientific notation to simplify large and small numbers.
In scientific notation, the power of 10 (exponent) equals the amount of places the decimal is shifted to give the digit number. For instance, 1,230,000,000 equals 1.23 × 10⁹. Scientific notation makes calculations easier. To multiply two numbers expressed as powers of ten, multiply the numbers in front and add the exponents.
