Scientific notation is a way of expressing very large or very small numbers in a more manageable form. It consists of a number between 1 and 10 multiplied by a power of 10. In this article, we will explore the concept of scientific notation and check whether each of the given numbers is in scientific notation.
What is Scientific Notation?
Scientific notation is a method of expressing numbers in the form of a product of a number between 1 and 10 and a power of 10. It is commonly used in mathematics, science, and engineering to simplify complex calculations and to express very large or very small numbers in a more manageable form.
The General Form of Scientific Notation
The general form of scientific notation is:
a × 10^n
where a is a number between 1 and 10, and n is an integer.
Examples of Scientific Notation
Here are some examples of numbers in scientific notation:
- 4.2 × 10^3
