Cube of 984

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 984 can be written as 984³, which is the exponential form. Or it can also be written in arithmetic form as 984 × 984 × 984.

In order to check whether a number is a cube number or not, we can use the following three methods, such as the multiplication method, a factor formula (a³), or by using a calculator. These three methods will help students to cube 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 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. \[ 984³ = 984 \times 984 \times 984 \] Step 2: You get 952,956,032 as the answer. Hence, the cube of 984 is 952,956,032.

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 984 into two parts. Let a = 900 and b = 84, so a + b = 984 Step 2: Now, apply the formula (a + b)³ = a³ + 3a²b + 3ab² + b³ Step 3: Calculate each term \[ a³ = 900³ \] \[ 3a²b = 3 \times 900² \times 84 \] \[ 3ab² = 3 \times 900 \times 84² \] \[ b³ = 84³ \] Step 4: Add all the terms together: \[ (a + b)³ = a³ + 3a²b + 3ab² + b³ \] \[ (900 + 84)³ = 900³ + 3 \times 900² \times 84 + 3 \times 900 \times 84² + 84³ \] \[ 984³ = 729,000,000 + 204,120,000 + 19,051,200 + 592,704 \] \[ 984³ = 952,956,032 \] Step 5: Hence, the cube of 984 is 952,956,032.

To find the cube of 984 using a calculator, input the number 984 and use the cube function (if available) or multiply 984 × 984 × 984. This operation calculates the value of 984³, resulting in 952,956,032. It’s a quick way to determine the cube without manual computation. Step 1: Ensure the calculator is functioning properly. Step 2: Press 9 followed by 8 and 4 Step 3: If the calculator has a cube function, press it to calculate 984³. Step 4: If there is no cube function on the calculator, simply multiply 984 three times manually. Step 5: The calculator will display 952,956,032.

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 equals 8. Cube Root: The cube root of a number is a value that, when multiplied by itself three times, gives the original number. It is denoted by the radical symbol with a small 3, ∛x. Perfect Cube: A number that can be expressed as the cube of an integer. For example, 27 is a perfect cube because it can be expressed as 3³.
