Solving the Cubic Equation: Exploring the Possible Values of xx

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 x3=250x^3=250 and explore the possible values of xx 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 x3=yx^3 = y, where xx is the cubic root of yy. For example, the cubic root of 2727 is 33, because 33=273^3 = 27.

Solving the Equation x3=250x^3=250

Now that we have a basic understanding of cubic roots, let's focus on solving the equation x3=250x^3=250. To find the possible values of xx, we need to isolate xx 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 xx. We can also consider the negative value of the cubic root, which is represented as 2503-\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 xx that satisfy the equation. By factoring 250250 into its prime factors, we can rewrite the equation as x3=532x^3 = 5^3 \cdot 2.

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

This gives us another possible value of xx, which is 5235 \sqrt[3]{2}. We can also consider the negative value of this expression, which is 523-5 \sqrt[3]{2}.

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

Evaluating the Options

Now that we have explored the possible values of xx that satisfy the equation x3=250x^3=250, let's evaluate the options provided.

  • A. 2503-\sqrt[3]{250}: This is a possible value of xx, as we discussed earlier.
  • B. 2503\sqrt[3]{250}: This is also a possible value of xx, as we discussed earlier.
  • C. 5235 \sqrt[3]{2}: This is another possible value of xx, as we discussed earlier.
  • D. 523-5 \sqrt[3]{2}: This is also a possible value of xx, as we discussed earlier.
  • E. 5235 \sqrt[3]{2}: This option is incorrect, as we have already discussed that the correct value is 5235 \sqrt[3]{2}, not 5235 \sqrt[3]{2}.

Conclusion

In conclusion, the possible values of xx that satisfy the equation x3=250x^3=250 are 2503-\sqrt[3]{250}, 2503\sqrt[3]{250}, 5235 \sqrt[3]{2}, and 523-5 \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.
