Answer 1

To multiply the expressions \(5a^2b^5c^3\) and \(-4a^7c^5\), we can follow these steps:

1. **Multiply the coefficients**:
\[
5 \cdot (-4) = -20
\]

2. **Multiply the variables by adding their exponents**:
- For \(a\):
\[
a^2 \cdot a^7 = a^{2+7} = a^9
\]
- For \(b\):
\[
b^5 \text{ (there is no } b \text{ in the second expression, so it remains as } b^5)
\]
- For \(c\):
\[
c^3 \cdot c^5 = c^{3+5} = c^8
\]

Now, combine all the results:
\[
-20a^9b^5c^8
\]

Thus, the final answer is:
\[
\text{negative } 20a^9b^5c^8
\]

The response that corresponds to this result is:
\[
\text{negative } 20 a^{9} b^{5} c^{8}
\]
