What is the formula for calculating square?
Square is one of the basic operations in mathematics and is widely used in many fields such as geometry, algebra, and physics. This article will introduce the square calculation formula and its application scenarios in detail, and provide you with a comprehensive analysis based on the hot topics and hot content on the entire network in the past 10 days.
1. Calculation formula of square
Square refers to the result of multiplying a number by itself, and its calculation formula is as follows:
| formula | Example |
|---|---|
| a² = a × a | 3² = 3 × 3 = 9 |
| (a + b)² = a² + 2ab + b² | (2 + 3)² = 4 + 12 + 9 = 25 |
| (a - b)² = a² - 2ab + b² | (5 - 2)² = 25 - 20 + 4 = 9 |
2. Square application scenarios
Square operations are widely used in daily life and scientific research. Here are a few typical examples:
| Application areas | Description |
