alex41 [277]

The question is incomplete. Here is the complete question:

Mr.yueng graded his students math quizzes students came up with four different answers when solving the equation x3=22. Which answers is correct.

(A) \frac{22}{3}

(B) \sqrt[3]{22}

(C) \pm \sqrt[3]{22}

(D) \sqrt{22}

Answer:

(B) \sqrt[3]{22}

Step-by-step explanation:

Given:

The equation to solve is given as:

x^3=22

Here, the left hand side of the equation has a variable 'x' in exponent form. So, in order to solve for 'x', we have to eliminate the exponent.

For removing the exponent, we have to take cubic root on both the sides. As we know that,

\sqrt[n]{x^n} =x

So, taking cubic root on both the sides, we get

\sqrt[3]{x^3}=\sqrt[3]{22}\\\\x=\sqrt[3]{22}

Therefore, the second student has written the correct answer and hence the correct option is (B).
