we have

\frac{b^{-2}} {ab^{-3}}

we know that

\frac{b^{-2}} {ab^{-3}} =(\frac{1}{b^{2}})( \frac{1}{a})( b^{3})\\ \\=\frac{b^{3}}{ab^{2}} \\ \\= \frac{b}{a}

therefore

<u>the answer is the option </u>

\frac{b}{a}

The moon is about 382,500km away from Earth. This distance actually varies by about 22,500km. What are the maximum and minimum d
KiRa [710]

Answer:

The minimum distance to the moon is of 360,000 km and the maximum distance is of 405,000 km

Step-by-step explanation:

The maximum distance is found adding the variation.

The minimum distance is found subtracting the variation.

We have that:

Distance: 382,500 km

Variation: 22,500 km

So

Maximum distance: 382500 + 22500 = 405,000 km

Minimum distance: 382500 - 22500 = 360,000 km

The minimum distance to the moon is of 360,000 km and the maximum distance is of 405,000 km
