Let's rewrite the given polynomial in standard form. The standard form of a polynomial lists terms in descending powers of $x$.

Given polynomial:

$x - 3 + 10x^3 - \frac{x^5}{9}$

To express it in standard form, arrange the terms by powers of $x$, from the highest power to the lowest:

$-\frac{x^5}{9} + 10x^3 + x - 3$

The standard form of the polynomial is:

$-\frac{1}{9}x^5 + 10x^3 + x - 3$
