According to the Fundamental Theorem of Algebra, a polynomial of degree \( n \) has exactly \( n \) roots, counting multiplicities, in the complex number system. The term \( 8x^5 \) indicates that the polynomial is of degree 5.

Therefore, the correct statement is:

**The equation has at least 5 roots.**

This means that the polynomial must have exactly 5 roots (some of them may be complex or repeated). Hence, it's not guaranteed that all roots are real, nor does it imply an odd number of real roots specifically.
