A number we multiply by itself three times to get the original number is its cube root. It has various uses in real life, such as finding the volume of cube-shaped objects and designing structures. We will now find the cube root of -2197 and explain the methods used.

What is the Cube Root of -2197?

We have learned the definition of the cube root. Now, let’s learn how it is represented using a symbol and exponent. The symbol we use to express the cube root is the radical sign (∛), and the exponent we use is ⅓. In exponential form, ∛(-2197) is written as (-2197)^(1/3). The cube root is just the opposite operation of finding the cube of a number. For example: Assume ‘y’ as the cube root of -2197, then y^3 can be -2197. Since -2197 is a perfect cube, the cube root of -2197 is exactly -13.

Finding the Cube Root of -2197

Finding the cube root of a number is to identify the number that must be multiplied three times resulting in the target number. Now, we will go through the different ways to find the cube root of -2197. The common methods we follow to find the cube root are given below: - Prime factorization method - Approximation method - Subtraction method - Halley’s method To find the cube root of a perfect cube like -2197, the prime factorization method is straightforward and effective.

Cube Root of -2197 by Prime Factorization

Let's find the cube root of -2197 using the prime factorization method. Firstly, we find the prime factors of 2197: 2197 = 13 × 13 × 13 Since -2197 is negative, its cube root will also be negative. Therefore, the cube root of -2197 is -13.

Common Mistakes and How to Avoid Them in the Cube Root of -2197

Finding the perfect cube of a number without any errors can be a difficult task for students. This happens for many reasons. Here are a few mistakes the students commonly make and the ways to avoid them:

Problem 1

Imagine you have a cube-shaped toy that has a total volume of -2197 cubic centimeters. Find the length of one side of the cube equal to its cube root.

Okay, lets begin

Side of the cube = ∛(-2197) = -13 units

Explanation

To find the side of the cube, we need to find the cube root of the given volume. Therefore, the side length of the cube is exactly -13 units.

Problem 2

A company has -2197 cubic meters of material. If they remove 169 cubic meters, how much material is left?

Okay, lets begin

The amount of material left is -2366 cubic meters.

Explanation

To find the remaining material, we need to subtract the used material from the total amount: -2197 - 169 = -2366 cubic meters.

Problem 3

A box holds -2197 cubic meters of volume. Another box holds a volume of 500 cubic meters. What would be the total volume if the boxes are combined?

Okay, lets begin

The total volume of the combined boxes is -1697 cubic meters.

Explanation

Explanation: Let’s add the volumes of both boxes: -2197 + 500 = -1697 cubic meters.

Problem 4

When the cube root of -2197 is multiplied by 2, calculate the resultant value. How will this affect the cube of the new value?

Okay, lets begin

2 × (-13) = -26 The cube of -26 = -17576

Explanation

When we multiply the cube root of -2197 by 2, the resultant value is -26. The cube of -26 results in a much larger negative volume because the cube increases exponentially.

Problem 5

Find ∛(-2197 + 343).

Okay, lets begin

∛(-2197 + 343) = ∛(-1854) ≈ -12.32

Explanation

As shown in the question ∛(-2197 + 343), we can simplify that by performing the addition: -2197 + 343 = -1854. Then we use this step: ∛(-1854) ≈ -12.32 to get the answer.
