Answer 2

Answer:

$\boxed{17.156}$

Step-by-step explanation:

A rational number can be written in the form p/q, where p and q are whole integers.

$\sqrt{15} \approx 3.87298334621...\neq \frac{p}{q}$

$2.6457513110... \neq \frac{p}{q}$

$17.156=\frac{4289}{250}$

$\sqrt[3]{85} \approx 4.39682967216... \neq \frac{p}{q}$

17.156 is a rational number.
