1.989 x 10^30 in Standard Form
In scientific notation, numbers are expressed as a product of a number between 1 and 10, and a power of 10. This notation is useful for expressing very large or very small numbers in a concise and readable way. In this article, we will explore how to express 1.989 x 10^30 in standard form.
What is Standard Form?
In standard form, a number is expressed as:
a × 10^n
where:
- a is a number between 1 and 10 (known as the coefficient)
- 10 is the base number
- n is an integer (known as the exponent)
Converting 1.989 x 10^30 to Standard Form
To express 1.989 x 10^30 in standard form, we can rewrite it as:
1.989 × 10^30 = 1.989 × 10^30
Since the coefficient (1.989) is already between 1 and 10, and the exponent (30) is an integer, the number is already in standard form.
Conclusion
In conclusion, 1.989 x 10^30 is already in standard form. It is a convenient way to express a very large number, making it easier to read and work with. By understanding standard form, we can simplify complex calculations and make them more manageable.
