Answer : The correct option is, x^{\frac{2}{3}}

Step-by-step explanation :

The given expression is :

(x^{\frac{4}{3}}\times x^{\frac{2}{3}})^{\frac{1}{3}}

First we have to solve the term present in the bracket.

Identity used : x^a\times x^b=x^{(a+b)}

\Rightarrow (x^{(\frac{4}{3}+\frac{2}{3})})^{\frac{1}{3}}

By the adding the powers of 'x', we get:

\Rightarrow (x^{\frac{6}{3}})^{\frac{1}{3}}

\Rightarrow (x^{2})^{\frac{1}{3}}

Now we have to use identity (x^{a})^b=x^{ab}, we get :

\Rightarrow (x)^{(2\times \frac{1}{3})}

\Rightarrow (x)^{\frac{2}{3}}

Therefore, the correct option is, x^{\frac{2}{3}}

Add 32 to both sides
12x≥6x+24
Subtract 6x.
6x≥24
Divide both sides by 6.
x≥4
