Cube of 137

A cube number is a value obtained by raising a number to the power of 3, or by multiplying the number by itself three times.

When you cube a positive number, the result is always positive.

When you cube a negative number, the result is always negative.

This is because a negative number multiplied by itself three times results in a negative number.

The cube of 137 can be written as 137³, which is the exponential form.

Or it can also be written in arithmetic form as 137 × 137 × 137.

In order to check whether a number is a cube number or not, we can use the following three methods: multiplication method, a factor formula (a³), or by using a calculator. These three methods will help cube the numbers faster and easier without feeling confused or stuck while evaluating the answers.

• By Multiplication Method
   
• Using a Formula
   
• Using a Calculator

The multiplication method is a process in mathematics used to find the product of two numbers or quantities by combining them through repeated addition. It is a fundamental operation that forms the basis for more complex mathematical concepts.

Step 1: Write down the cube of the given number. 137³ = 137 × 137 × 137

Step 2: You get 2,573,737 as the answer. Hence, the cube of 137 is 2,573,737.

The formula (a + b)³ is a binomial formula for finding the cube of a number. The formula is expanded as a³ + 3a²b + 3ab² + b³.

Step 1: Split the number 137 into two parts, as a and b. Let a = 130 and b = 7, so a + b = 137

Step 2: Now, apply the formula (a + b)³ = a³ + 3a²b + 3ab² + b³

Step 3: Calculate each term a³ = 130³ 3a²b = 3 × 130² × 7 3ab² = 3 × 130 × 7² b³ = 7³

Step 4: Add all the terms together: (a + b)³ = a³ + 3a²b + 3ab² + b³ (130 + 7)³= 130³ + 3 × 130² × 7 + 3 × 130 × 7² + 7³ 137³ = 2,197,000 + 355,300 + 63,700 + 343 137³ = 2,573,737

Step 5: Hence, the cube of 137 is 2,573,737.

To find the cube of 137 using a calculator, input the number 137 and use the cube function (if available) or multiply 137 × 137 × 137. This operation calculates the value of 137³, resulting in 2,573,737. It’s a quick way to determine the cube without manual computation.

Step 1: Ensure the calculator is functioning properly.

Step 2: Press 1 followed by 3 and 7

Step 3: If the calculator has a cube function, press it to calculate 137³.

Step 4: If there is no cube function on the calculator, simply multiply 137 three times manually.

Step 5: The calculator will display 2,573,737.

• The cube of any even number is always even, while the cube of any odd number is always odd.
   
• The product of two or more perfect cube numbers is always a perfect cube.
   
• A perfect cube can always be expressed as the product of three identical groups of equal prime factors.

• Binomial Formula: It is an algebraic expression used to expand the powers of a number, written as (a + b)ⁿ, where ‘n’ is a positive integer raised to the base. The formula is used to find the square and cube of a number.
   
• Cube of a Number: Multiplying a number by itself three times is called the cube of a number.
   
• Exponential Form: It is a way of expressing numbers using a base and an exponent (or power), where the exponent value indicates how many times the base is multiplied by itself. For example, 2³ represents 2 × 2 × 2, which equals 8.
   
• Perfect Cube: A number that can be expressed as the cube of an integer. For instance, 8 is a perfect cube because it equals 2³.
   
• Volume of a Cube: The amount of space inside a cube, calculated using the formula V = side³, where 'side' is the length of one side of the cube.
