Answer
The statement is false.
To make it true, change "is" to "is not".
Work Step by Step
A binomial is a polynomial with two terms.
These terms contains powers of $x,$ but the exponents are negative integers.
$\displaystyle \frac{1}{5}x^{-2}+\frac{1}{3}x^{-1}$.
A polynomial has terms in which the exponents of variables must be nonnegative integers.
This expression is not a polynomial. Consequently, it is not a binomial.
So, the statement is false.
To make it true, change "is" to "is not"
