Answer:

[tex]x>5[/tex]

Step-by-step explanation:

We are asked to find an integer x such that [tex]\frac{x^3}{5}>x^2[/tex].

First of all, we will multiply both sides of inequality by 5.

[tex]\frac{x^3}{5}>x^2[/tex]  

[tex]\frac{x^3}{5}*5>5*x^2[/tex]  

[tex]x^3>5x^2[/tex]  

Divide both sides by [tex]x^2[/tex]:

[tex]\frac{x^3}{x^2}>\frac{5x^2}{x^2}[/tex]

[tex]x>5[/tex]

Therefore, the value of x is any number greater than 5.
