start fraction 10 w cubed over r superscript 4 baseline end fraction

Answer 1

To simplify the expression \(\frac{10 r^{-2}}{r^2 w^{-3}}\), we can follow these steps:

1. Rewrite the expression by removing the negative exponents:
\[
\frac{10}{r^2} \cdot \frac{w^3}{1} = \frac{10 w^3}{r^2}
\]

2. Since the denominator has \(r^2\) which is \(r^{2}\) and the numerator has \(r^{-2}\), combine the powers of \(r\):
\[
\frac{10 w^3}{r^2} = \frac{10}{r^{2-(-2)}} w^3 = \frac{10 w^3}{r^4}
\]

Now, we end up with:
\[
\frac{10 w^3}{r^4}
\]

Thus, the simplified expression is:
\[
\frac{10 w^3}{r^4}
\]

The correct response is: **start fraction 10 w cubed over r superscript 4 baseline end fraction**.
