We know that 512=2^9, which implies that (-2)^9=-512 (since 9 is odd). Thus -2 is one of the 9th root of -512.
There are 8 (or 4 pairs of) other roots that are excluded because they are complex.
Therefore -2 is the only real 9th root of -512.

Answer:
The value of <em>s</em> that will make <em>p</em> = 0 is 80.
Step-by-step explanation:
The equation used to describe the relationship between amount of airborne particulate pollution from a power plant and wind speed is:
Compute the value(s) of <em>s</em> for which the value of <em>p</em> = 0 as follows:
Since wind cannot travel in negative speed, the value of <em>s</em> is 80.
