Rationalize denominator and s (3)/(x^3) III

To rationalize the denominator of the expression $\frac{3}{x^3}$, we need to eliminate the variable $x$ from the denominator. We can do this by multiplying both the numerator and denominator by $x^2$.<br /><br />$\frac{3}{x^3} \times \frac{x^2}{x^2} = \frac{3x^2}{x^5}$<br /><br />Therefore, the rationalized form of $\frac{3}{x^3}$ is $\frac{3x^2}{x^5}$.
