When we talk about raising a number to a power, we’re referring to the process of multiplying that number by itself a specified number of times. In the case of 20 raised to the power of 2, it means we will multiply 20 by itself.
So, mathematically, it can be expressed as:
202 = 20 × 20
Now, let’s perform the multiplication:
- 20 × 20 = 400
Therefore, the answer to 20 raised to the power of 2 is 400.
This concept is a fundamental part of mathematics known as exponentiation, which is used in various applications, from simple calculations to complex equations in fields such as science and engineering.
