Cube Root of 9261

Cube Root of 9261 is 21. Cube Root is a number when multiplied by itself twice (raised to the power of three) gives the original number. The cube root of an integer “x,” which is represented by the symbol ∛x. This is the opposite of cubing a number. For instance, since 2³ (2 raised to the power of 3) equals 8 this implies the cube root of 8 is 2.

In this article, we will learn what is cube root of 9261 and the different ways to find the cube root of 9261.

What is the Cube Root of 9261?

Cube Root of 9261 is a value obtained when 9261 is raised to power 1/3. Cube Root of 9261 is 21. It means when 21 is multiplied by 21 twice then the answer is 9261. We can express this product as 21 × 21 × 21 = 9261.

The cube root of 9261 can be expressed in following ways:

How to Calculate the Value of the Cube Root of 9261?

To find the cube root of 9261 we can use the following methods:

• Prime Factorization Method
• Long Division Method
• Repeated Subtraction Method
• Estimation Method

Let’s study these methods in detail below:

Cube Root of 9261 By Prime Factorization

We can determine the cube root of 9261 by Prime Factorization method using the following steps:

Step 1: Find the Prime Factorization of the Number 9261,

Thus, 9261 = 3 × 3 × 3 × 7 × 7 × 7 = 3³ × 7³

Step 2: Make a group of three like numbers. Hence there will be two groups containing three 3 and three 7.

Step 3: Now ∛9261 = ∛(3³ × 7³).

Step 4: From law of exponents (3³ × 7³)^1/3 = 3 × 7= 21.

We can also say that for each three similar prime numbers take out one out of the cube root.

Hence, for three 3 and three 7, there will be one 3 and one 7 in the form 3 × 7 = 21

Thus the cube root of 9261 is 21.

Cube root of 9261 by Repeated Subtraction

To find the cube root of 9261, successively subtract 9261 by numbers such as 1, 7, 19, 37, 61, 91, 127, and so on. The number of steps in which the difference becomes zero is the cube root.

Let’s see how it proceeds:

• 9261 − 1 = 9260
• 9260 − 7 = 9253
• 9253 − 19 = 9234
• 9234 − 37 = 9197
• 9197 − 61 = 9136
• 9136 − 91 = 9045
• 9045 − 127 = 8918
• 8918 − 169 = 8749
• 8749 − 217 = 8532
• 8532 − 271 = 8261
• 8261 − 331 = 7930
• 7930 − 397 = 7533
• 7533 − 469 = 7064
• 7064 − 547 = 6517
• 6517 − 631 = 5886
• 5886 − 727 = 5159
• 5159 − 811 = 4348
• 4348 − 907 = 3441
• 3441 − 1019 = 2422
• 2422 − 1141 = 1281
• 1281 − 1281 = 0

Here, we see that the we started subtracting from 9261 and the difference becomes zero in the twenty-first step . Hence, the cube root of 9261 is 21 .

Cube Root of 9261 by Estimation Method

In estimation method we will try to get the result by approximation. Let’s learn how to find cube root of 9261

• We know that cube of 10 is 1000 and we have to find cube root of 9261 so certainly its cube root is grater than 10
• Next we find cube of 20 which is 8000, with this come more closer and find that cube root of 9261 is greater than 20
• Next we find that cube of 30 is 27000 which is much larger than 9261. Hence we are now assured that cube root of 9261 is between 20 and 30 and to be precise closer to 20.
• Now since, the unit digit of 9261 is 1, so its cube root must have unit digit 1.
• Hence, we will try to find cube of 21 which is 21 × 21 × 21 = 9261

So, using estimation method we find that the cube root of 9261 is 21.

Is Cube Root of 9261 Rational or Irrational?

The cube root of 9261 is equal to 21 i.e. ∛9261 = 21. Now we can represent 21 in the form of p/q where p and q are integers and q is not equal to 0 i.e. 21/1.

In this case, the denominator is 1 and the numerator is 21. This proves that the cube root of 9261 is a rational number.
