10 to the 9th power, mathematically expressed as 109, is a calculation that represents 10 multiplied by itself 9 times. This is part of a larger category of mathematics known as exponentiation, which deals with the operation of raising a number to a power.
When you calculate 109, you start with 10:
- 10 x 10 = 100 (102)
- 100 x 10 = 1000 (103)
- 1000 x 10 = 10000 (104)
- 10000 x 10 = 100000 (105)
- 100000 x 10 = 1000000 (106)
- 1000000 x 10 = 10000000 (107)
- 10000000 x 10 = 100000000 (108)
- 100000000 x 10 = 1000000000 (109)
The final result of 109 is 1,000,000,000, or one billion. This number is often used in different contexts, such as in scientific notation, where it can be represented as 1 x 109. Learning how to work with powers of 10 is foundational in mathematics, particularly in fields like physics and engineering, where large numbers frequently arise.
In conclusion, 109 equals 1,000,000,000, a staggering figure that showcases the power of exponential growth.
