Square of 630

The square of a number is the product of the number itself. The square of 630 is 630 × 630. The square of a number can end in 0, 1, 4, 5, 6, or 9. We write it in math as (630²), where 630 is the base and 2 is the exponent. The square of a positive and a negative number is always positive. For example, (5² = 25); ((-5)² = 25)

The square of 630 is 630 × 630 = 396,900

Square of 630 in exponential form: (630²⁾

Square of 630 in arithmetic form: 630 × 630

The square of a number is multiplying the number by itself. So let’s learn how to find the square of a number. These are the common methods used to find the square of a number.

1. By Multiplication Method
2. Using a Formula
3. Using a Calculator

In this method, we will multiply the number by itself to find the square. The product here is the square of the number. Let’s find the square of 630.

Step 1: Identify the number. Here, the number is 630.

Step 2: Multiplying the number by itself, we get, 630 × 630 = 396,900.

The square of 630 is 396,900.

In this method, the formula, (a²) is used to find the square of the number. Where \(a\) is the number.

Step 1: Understanding the equation Square of a number = (a²) 

(a² = a × a)

Step 2: Identifying the number and substituting the value in the equation.

Here, ‘a’ is 630. So: (630² = 630 × 630 = 396,900\)

Using a calculator to find the square of a number is the easiest method. Let’s learn how to use a calculator to find the square of 630.

Step 1: Enter the number in the calculator Enter 630 in the calculator.

Step 2: Multiply the number by itself using the multiplication button (×). That is 630 × 630.

Step 3: Press the equal to button to find the answer. Here, the square of 630 is 396,900.
