Evaluate the expression:
[tex](-8)^{1 / 3}[/tex]

Select the correct choice:
A. -2
B. 2
C. -1
D. 1


Sagot :

To evaluate the expression \((-8)^{1/3}\), we are looking for the cube root of \(-8\).

1. Formulate the Problem:
The cube root of a number \(x\) is a number \(y\) such that \(y^3 = x\). Here, we need to find the number \(y\) such that \(y^3 = -8\).

2. Understanding Cube Roots of Negative Numbers:
For negative numbers, the cube root can have both a real and an imaginary component.

3. Calculation:
The cube root of \(-8\) can be complex. When dealing with complex numbers, the principal cube root takes into account the magnitude and argument (angle) in the complex plane.

4. Result:
The result of the cube root of \(-8\) is:

[tex]\[ (1.0000000000000002 + 1.7320508075688772j) \][/tex]

In conclusion, the correct choice for evaluating \((-8)^{1/3}\) is:

[tex]\[ (1.0000000000000002 + 1.7320508075688772j) \][/tex]
