Solving the Cubic Equation: Exploring the Possible Values of $x$

When it comes to solving cubic equations, it's essential to understand the properties of cubic roots and how they can be manipulated to find the possible values of the variable. In this article, we'll delve into the equation $x^3=250$ and explore the possible values of $x$ that satisfy this equation.

Understanding Cubic Roots

Before we dive into the solution, let's take a moment to understand what cubic roots are. A cubic root of a number is a value that, when multiplied by itself three times, gives the original number. In mathematical notation, this can be represented as $x^3 = y$ , where $x$ is the cubic root of $y$ . For example, the cubic root of $27$ is $3$ , because $3^3 = 27$ .

Solving the Equation $x^3=250$

Now that we have a basic understanding of cubic roots, let's focus on solving the equation $x^3=250$ . To find the possible values of $x$ , we need to isolate $x$ by taking the cubic root of both sides of the equation.

x^3 = 250
x = \sqrt[3]{250}

However, this is not the only possible value of $x$ . We can also consider the negative value of the cubic root, which is represented as $-\sqrt[3]{250}$ .

x = -\sqrt[3]{250}

Exploring Other Possible Values

In addition to the positive and negative cubic roots, we can also consider other possible values of $x$ that satisfy the equation. By factoring $250$ into its prime factors, we can rewrite the equation as $x^3 = 5^3 \cdot 2$ .

x^3 = 5^3 \cdot 2
x = 5 \sqrt[3]{2}

This gives us another possible value of $x$ , which is $5 \sqrt[3]{2}$ . We can also consider the negative value of this expression, which is $-5 \sqrt[3]{2}$ .

x = -5 \sqrt[3]{2}

Evaluating the Options

Now that we have explored the possible values of $x$ that satisfy the equation $x^3=250$ , let's evaluate the options provided.

A. $-\sqrt[3]{250}$ : This is a possible value of $x$ , as we discussed earlier.
B. $\sqrt[3]{250}$ : This is also a possible value of $x$ , as we discussed earlier.
C. $5 \sqrt[3]{2}$ : This is another possible value of $x$ , as we discussed earlier.
D. $-5 \sqrt[3]{2}$ : This is also a possible value of $x$ , as we discussed earlier.
E. $5 \sqrt[3]{2}$ : This option is incorrect, as we have already discussed that the correct value is $5 \sqrt[3]{2}$ , not $5 \sqrt[3]{2}$ .

Conclusion

In conclusion, the possible values of $x$ that satisfy the equation $x^3=250$ are $-\sqrt[3]{250}$ , $\sqrt[3]{250}$ , $5 \sqrt[3]{2}$ , and $-5 \sqrt[3]{2}$ . These values can be obtained by taking the cubic root of both sides of the equation and considering the positive and negative values of the cubic root.
