The product of multiplying an integer by itself is the square of a number. The square is used in programming, calculating areas, and so on. In this topic, we will discuss the square of 890.
The square of a number is the product of the number itself.
The square of 890 is 890 × 890.
The square of a number always ends in 0, 1, 4, 5, 6, or 9.
We write it in math as 890², where 890 is the base and 2 is the exponent.
The square of a positive and a negative number is always positive.
For example, 5² = 25; -5² = 25.
The square of 890 is 890 × 890 = 792,100.
Square of 890 in exponential form: 890²
Square of 890 in arithmetic form: 890 × 890
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.
In this method, we multiply the number by itself to find the square. The product here is the square of the number. Let’s find the square of 890.
Step 1: Identify the number. Here, the number is 890.
Step 2: Multiplying the number by itself, we get, 890 × 890 = 792,100.
The square of 890 is 792,100.
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 890.
So: 890² = 890 × 890 = 792,100
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 890.
Step 1: Enter the number in the calculator Enter 890 in the calculator.
Step 2: Multiply the number by itself using the multiplication button (×) That is 890 × 890
Step 3: Press the equal to button to find the answer
Here, the square of 890 is 792,100.
Tips and tricks make it easy for students to understand and learn the square of a number. To master the square of a number, these tips and tricks will help students.
Mistakes are common among kids when doing math, especially when it is finding the square of a number. Let’s learn some common mistakes to master the squaring of a number.
Find the length of the square, where the area of the square is 792,100 cm².
The area of a square = a² So, the area of a square = 792,100 cm² So, the length = √792,100 = 890. The length of each side = 890 cm
The length of a square is 890 cm.
Because the area is 792,100 cm², the length is √792,100 = 890.
Sarah is designing a square garden with a length of 890 feet. The cost to fence a foot is 5 dollars. Then how much will it cost to fence the full garden?
The length of the garden = 890 feet The cost to fence 1 square foot of the garden = 5 dollars. To find the total cost to fence, we find the area of the garden, Area of the garden = area of the square = a² Here a = 890 Therefore, the area of the garden = 890² = 890 × 890 = 792,100. The cost to fence the garden = 792,100 × 5 = 3,960,500. The total cost = 3,960,500 dollars
To find the cost to fence the garden, we multiply the area of the garden by the cost to fence per foot.
So, the total cost is 3,960,500 dollars.
Find the area of a circle whose radius is 890 meters.
The area of the circle = 2,487,574.6 m²
The area of a circle = πr²
Here, r = 890
Therefore, the area of the circle = π × 890² = 3.14 × 890 × 890 = 2,487,574.6 m².
The area of the square is 792,100 cm². Find the perimeter of the square.
The perimeter of the square is 3,560 cm.
The area of the square = a²
Here, the area is 792,100 cm²
The length of the side is √792,100 = 890
Perimeter of the square = 4a
Here, a = 890
Therefore, the perimeter = 4 × 890 = 3,560 cm.
Find the square of 891.
The square of 891 is 793,881.
The square of 891 is multiplying 891 by 891.
So, the square = 891 × 891 = 793,881.
