The symbol 30 squared represents the mathematical operation of squaring a number. When a number is squared, it is multiplied by itself. For example, if we square the number 3, we get 3 x 3 = 9.
To find the square of 30, we simply multiply 30 by itself. So, 30 squared is equal to 30 x 30, which gives us the answer of 900.
To find the square of a number, there are a few helpful tips that can make the process easier:
Understand what squaring means: Squaring a number is the same as multiplying it by itself. It is a way to find the area of a square with side length equal to the given number.
Translate squaring into a multiplication equation: To square a number, write it as a multiplication equation with the number multiplied by itself.
Insert numbers into multiplication equations: Replace the variable with the given number and perform the multiplication to find the square.
Finally, get the answer: After performing the multiplication, you will have the square of the given number.
To find the square of 30, we follow these steps:
Write the multiplication equation: 30 x 30.
Perform the multiplication: 30 x 30 = 900.
The answer is 900. Therefore, 30 squared is equal to 900.
In mathematics, the term "square" refers to the operation of multiplying a number by itself. It is called square because it is often used to find the area of a square, where the side length is equal to the given number.
The symbol for square is a small superscript 2 written after the number. For example, 30 squared is written as 30^2.
Let's solve an example problem to further understand squares:
Problem: Find the square of 12.
Solution: To find the square of 12, we follow the same steps as before:
Write the multiplication equation: 12 x 12.
Perform the multiplication: 12 x 12 = 144.
The answer is 144. Therefore, 12 squared is equal to 144.
Can negative numbers be squared? Yes, negative numbers can be squared. When a negative number is squared, the result is always positive.
What is the square of 0? The square of 0 is 0, as any number multiplied by 0 is 0.
What is the square of 1? The square of 1 is 1, as any number multiplied by 1 is itself.
What is the square of a fraction? To square a fraction, square both the numerator and the denominator separately.
